Introduction - Cyflwyniad
Using the past tense will help you describe past events, such as:
- what you did at the weekend, and
- what you did during the holidays.
It is important that you can use the correct past tense form to make it clear who did the action as well as when it took place.

How to use two key irregular Welsh verbs, 'mynd' (to go) and 'cael' (to have), in the past tense.
Most verbs in Welsh are 'regular verbs'. This means they all follow a similar pattern when we use them.
But there are other verbs that behave a bit differently. We call these irregular verbs.
Irregular verbs don't follow the same patterns as regular verbs.
Some of the most important irregular verbs in Welsh are:
mynd
cael
gwneud
Let's look at how 'mynd' and 'cael' behave when we talk about the past:
'Mynd' becomes 'Es i' = 'I went'.
'Es i i'r parc ddoe.'
'Es i adref.'
'Cael' becomes 'Ces i' = 'I had'.
'Ces i anrheg.'
'Ces i siocled poeth.'
Here's how we use 'mynd' to talk about the past:
Es i
Est ti
Aeth e / Aeth o
Aeth hi
Aeth Siôn
Aethon ni
Aethoch chi
Aethon nhw
'Aeth Siôn i'r dref.'
'Aethon nhw i wylio'r gêm.'
And here's how we use 'cael' = 'to have' when we talk about the past:
Ces i
Cest ti
Cafodd e / Cafodd o
Cafodd hi
Cafodd Siôn
Cawson ni
Cawsoch chi
Cawson nhw
'Cafodd hi hwyl yn y parti.'
'Cawson ni amser da ar ein gwyliau.'
Knowing how to use irregular verbs comes in very handy!
Some Welsh verbs are irregular in the past tense.
Unlike regular verbs, verbs like ‘mynd’ (to go) and ‘cael’ (to have) do not follow the usual pattern when they change into the past tense.
Each irregular past tense form must be learnt individually, as the whole verb changes depending on who did the action.
Be aware! Because ‘mynd’ and ‘cael’ are irregular verbs, you cannot change them by simply adding a past tense verb ending. You will need to learn them individually so you can use them when speaking or writing in Welsh.
Although most Welsh verbs are regular, and follow a similar pattern, some verbs are irregular.
They don't follow the usual pattern, so you need to learn their different forms.
Two of the most important irregular verbs in Welsh are 'mynd' (to go) and 'cael' (to have).
‘Mynd’ - (to) Go
When using ‘mynd’ in the past tense, if you are doing the action, you will start your sentence with ‘Es i’.
It means ‘I went’.
For example:
Sorry, something went wrongCheck your connection, refresh the page and try again.(I went to the restaurant).
Sorry, something went wrongCheck your connection, refresh the page and try again.(I went for a walk).

Different forms
The form of ‘mynd’ you will need to use changes depending on who is doing the action.
Singular:
| I went | Es i |
| You went | Est ti |
| He went | Aeth o / Aeth e |
| She went | Aeth hi |
To name the person doing the action, you will use the following form:
Aeth Siôn(Siôn went).
Plural:
| We went | Aethon ni |
| You went | Aethoch chi |
| They went | Aethon nhw |
Forming a sentence
Once you know which form of ‘mynd’ you need, you will often need to add ‘i’ after it.
‘i’ translates as ‘to’.
Examples:
Es i+i+Llandudno → Sorry, something went wrongCheck your connection, refresh the page and try again.(I went to Llandudno)
Aethon nhw+i+Wrecsam → Sorry, something went wrongCheck your connection, refresh the page and try again.(I went to Wrexham)

This isn’t always the case, here are some examples that don’t need ‘i’:
Sorry, something went wrongCheck your connection, refresh the page and try again.(She went to the car)
Sorry, something went wrongCheck your connection, refresh the page and try again.(We went on the train)
‘Cael’ - (to) Have
When using ‘cael’ in the past tense, if you are doing the action, you will start your sentence with ‘Ces i’.
It means ‘I had’.
For example:
Ces i sgwrs.(I had a chat).
Ces i hwyl.(I had fun).

Different forms
The form of ‘cael’ you will need to use changes depending on who is doing the action.
Singular:
| I had | Ces i |
| You had | Cest ti |
| He had | Cafodd o / Cafodd e |
| She had | Cafodd hi |
To name the person doing the action, you will use the following form:
Cafodd Sian(Sian had).
Plural:
| We had | Cawson ni |
| You had | Cawsoch chi |
| They had | Cawson nhw |
Forming a sentence
Once you know which form of ‘cael’ add the rest of the information needed to complete your sentence.
Examples:
Ces i+amser da → Ces i amser da(I had a good time)
Cawson ni+barti pen-blwydd → Cawson ni barti pen-blwydd(We had a birthday party)
Remember:
There’s no shortcut to remembering the past tense of 'cael' and 'mynd'.
Just keep practising, and they’ll soon become familiar.
They are two of the most important verbs in Welsh, so you’re likely to use them a lot!
