What are ordinal numbers?
Ordinal numbers are used to show us how something or someone is ranked on a list and what their exact position is. They are only used to refer to a position but not a quantity which is what we use cardinal numbers for. Majority of the ordinal numbers follow the same structure with the exception from the written version of 1 to 4 as we can see from the table below.
Ordinal numbers chart
| Ordinal number | Written form |
|---|---|
| 1st | First |
| 2nd | Second |
| 3rd | Third |
| 4th | Fourth |
| 5th | Fifth |
| 6th | Sixth |
| 7th | Seventh |

Ordinal numbers examples
- She was my first girlfriend.
- This is my second attempt.
- We completed the third assignment.
- My final position was thirty-fourth.
- It is my sixty-eighth anniversary.
Ordinal numbers grammar
Ordinal numbers and their written form are rather specific thus it is important to pay attention to ensure the correct form is written.
1. The most special cases are the first three numbers:
| First | Twenty-first | Fifty-first | Two hundred and first |
| Second | Twenty-second | Sixty-second | Three hundred and second |
| Thid | Twenty-third | Sixty-third | Four hundred and twenty-third |
As we can see from the table the form for first, second, and third remains a constant regardless of where it is used in a positional manner.
2. The case of 11, 12, 13: While the ending number of them is the same as the one we discussed in the first example they are exception to the rule and always needs to be written in one specific way.
- Eleventh
- Twelfth
- Thirteenth
Cardinal and ordinal numbers
The main diffrence between the two is that cardinal numbers directly refer to a quantity whereas ordinal numbers only refer to a position but not quantity.
However, the two work hand in hand as excluding the exception all of the other ordinal numbers are formed by adding the suffix -th to the cardinal number.
Example:
| Cardinal number | Ordinal number |
|---|---|
| Seven | Seventh |
| Nine | Ninth |
| Twenty-four | Twenty-fourth |
| Thirty-five | Thirty-fifth |

What our students say
Unlike in other platforms, all our teachers are manually verified by our professional team. Trust in the experiences of our students.
Hi! I've been teaching English in Spain for the last 3 years and have lots of experience with Cambridge official exams (Pre A1- C1), conversation classes, help with General English and CLIL.
My teaching style is student-centered and tailored to your needs and goals. There's always plenty of talking time to practice any new grammar and vocabulary to focus on fluency and accuracy, as well as building confidence to naturally practice your new skills in conversation. The courses I create always revise previous learning points and integrate them with new material so that you don't just learn something once and never see it again.
I teach with a range of realia, textbook resources and online materials that have proven effective and engaging with my students in the past, but everything I use is adapted specifically for your areas of weakness and learning styles!
A. W.
I find that Beth was so easy to talk. I m always nervous when I speak English but talking to Beth I am not nervous because she has this power to let me just speak. She won’t rush to finish even the time is almost up. Is good. Hoping to take her class more and more. Her accent is easy to hear too!
Beth B.
Thank you Achilles! I had a great time teaching you in your first class and it was great to see you already making so much progress and gaining confidence! I'm looking forward to seeing you in your next class!
English teacher with 13 years teaching experience in Italy. Speaks English and Italian.
Hi, I'm Jason, I'm English and live in Central Italy where I teach English to students of all levels, all ages and all abilities. English for school, for exams or tests, for work or for business.
My methods are based on building your confidence to speak English, developing your listening skills so you can understand English and helping you understand the grammar rules of the English language.
Why in this way? Because my students have the best results when they are able to speak in English as soon as possible. Then, when you can converse in English and understand simple conversation you can develop all your language skills very quickly.
Of course, for some students, grammar and written English is a priority and I can help you develop these skills first if that is what you need.
For others they need to learn specific vocabulary for their work, I have given courses in business, medicine and tourism that can be adapted for all types of work situations.
I am teaching students from 3 to 70 years old and my lessons are adapted for every individual so they have the best opportunity to realize their goals.
If you are interested then please contact me for a chat and a free trial lesson.

I'm William and I'm a Belgian student who was looking for a teacher to improve my English because I have to pass a test in September before I may start a Master education at the university. I contacted Jason and we've had 2 lessons at this time. These lessons were very usefull and Jason explained everything to me when I had a question or when there was something I understood very well on that moment. So Jason is a very good teacher also very kind and he will help you a lot with a lot of passion.

Great teacher, lovely person, smart and open minded. I also like the fact that he is aware of cultural differences and his methodology of teaching is actually so effective. I was very happy to have selected him, he did an amazing job! If you are looking for a teacher who knows exactly what you should know before the exam, I strongly recommended contacting Tapas.

Hi! My name is Joyce and I am from Glasgow in Scotland. I’m looking forward to meeting you online to help you improve your English!
I have a degree in French and German, and have worked in tourism for over 30 years, living in many different parts of the world. I love learning about and getting to know different cultures.
I love travelling and have been fortunate enough to work as an overseas representative, and then manager, for British tour operators in such diverse places as Bulgaria, Spain, Jamaica, Italy, Austria, Paris, Thailand and Cancún, where our objective was always to provide the best possible service to our customers, the holidaymakers.
I then stayed in Cancún, spending over 15 years with Mexico’s principal travel company in the growing e-commerce sector, specialising in online sales and reservations, customer care and corporate travel.
Times are changing and looking for a new challenge I have taken the opportunity this year to add to my skills and have obtained certificates in Teaching English as a Foreign Language, and Teaching English Online. I’m really looking forward to putting these to good use in helping you to improve your English vocabulary, grammar and conversational skills. We will go at your pace, incorporating reading, writing, listening and speaking, with enjoyable interactive activities to make learning fun.

Hi, welcome to my profile!
My name is Alessia and I currently live in Italy. I spent a few years in the United States where I deepened my knowledge of English and American dialects. I am currently specializing in Spanish and German. Over the years, I have given private lessons in Italian, English, Spanish, and Japanese, with Japanese being the most requested at the moment. Regarding Japanese, I had the opportunity to teach the language at an American college with a native Japanese teacher, applying the method that they use to learn their own language. I will help you in a simple way; conversation is really important for learning a language, and a good method is even more fundamental. No days spent on textbooks are needed; consistency and fun during lessons are the most important parts of learning. You will see results right away! I am patient, flexible, and will adapt in every way to your personal needs. I look forward to seeing you on my profile for a trial lesson and discovering an easy and fun method to learn a language as soon as possible.

Ian M.
I am a BA in Education graduate, with vast experience in primary, secondary and higher education levels, as well as in other activities related to education. I believe I have a diverse background which makes me a very adaptable teacher and with a lot to offer.
Most of my experience is in high school ,in adult education and university students. I have been able to develop a good relationship with my students, which has translated to better communication and an altogether more rounded experience for them and myself. My lesson planning has always aimed to reflect my students’ needs and interest applied into useful communicative language structures that they can actually use in their lives.
In my last years as a teacher, I have focused on preparing test-takers for the TOEFL. It has been a completely different experience from what I have had before, but I have helped my students accomplish the desired scores in the proposed time.
I believe in making the learning of a new language something exciting and not frightening at all, but challenging and gratifying instead. My material is dynamic and keeps my students engaged and continuesly developing their communiation skills.
I am flexible with my students' time and shcedule; naturally, it is open for deliberation if needed. I look forward to helping you get to the desired goals you set foryourself!

Catherine is an excellent teacher and communicator. In our initial session, we had an extremely productive conversation about goals and expectations and what I was seeking with personal lessons in Spanish. This allowed her to tailor our first lesson to my needs. I learned so much! She helped substantially with pronunciation and verb conjugations. I look forward to our next sessions and continued learning. I highly recommend her to anyone who is looking to improve their language skills in Spanish and English, in particular.
