This post is the 8th instalment of the Welsh leg of my current Celtic challenge. It covers chapter 7 of Colloquial Welsh. For earlier instalments, please see Welsh Archives – Language Miscellany
I’ve used bold type below to highlight words affected by mutations, SM after words that induce soft mutation and SM before words affected by SM.
Imperfect of bod (‘be’)
Table 1 shows the imperfect of bod (‘be’), showing the form used (in singular S and plural P):
- for affirmative statements and questions;
- in more formal Welsh.
Table 1. Imperfect of bod
| Person / number | Affirmative / question | Formal |
| 1S | o’n i | roeddwn i |
| 2S | o’t ti | roeddet ti |
| 3S | oedd e / hi | roedd e / hi |
| 1P | o’n ni | roedden ni |
| 2P | o’ch chi | roeddech chi |
| 3P | o’n nhw | roedden nhw |
- to form the negative, append the negative ddim and optionally add /d/ at the start:
(d)o’n i ddim (‘I was not’) - for the negative of the formal form, replace the initial /r/ with /d/:
doedd e (‘he was not’) - for a formal question, delete the initial /r/:
oedden ni? (‘were we?’) - to answer ‘yes’ to a a question beginning with the imperfect of bod, use the form for a formal question, without the personal pronoun:
Q. O’ch chi yn y SMdre neithiwr
were you in the town last.night?
A. Oeddwn
Was.1P
‘yes = [I] was’ - to answer ‘no’, prefix nag to either spoken or written forms.
- to form a tag question, place on’d before the question form (with o without the following pronoun):
on’d oedd (hi)?
‘wasn’t it?’
Future of bod
Table 2 shows the future of bod (‘be’) in affirmative statements.
Table 2. Future of bod
| Person / number | Form | Person / number | Form |
| 1S | bydda i | 1P | byddwn ni |
| 2S | byddi di | 2P | byddwch chi |
| 3S | bydd e / hi | 3P | byddan nhw |
As is the case for all inflected verbs:
- to form questions, apply soft mutation to the verb, eg fydda i (‘will I be?’).
- to form negative statements, apply soft mutation to the verb and append the negative ddim, eg fydda i ddim (‘I will not be’).
- in colloquial Welsh, even the affirmative forms sometimes undergo soft mutation.
Other points:
- to answer ‘yes’, simply repeat the future of bod in the appropriate person and number.
- to answer ‘no’, use naSM, followed by the soft mutated future form of bod.
- in answers, the 1st person singular is often byddaf (with added /f/).
- to form tag questions, use on’ followed by the affirmative form (usually unmutated), with or without the pronoun following, eg on’ byddwyn (ni)? (‘won’t’ we?)
Imperfect and future of other verbs
To form the imperfect or future of other verbs, place the verbal noun after the imperfect or future of bod, linking them with the particle yn. Example:
oedd y SMbobol yn eistedd draw fan’na
were the people particle sit over there
‘the people were sitting over there’
bydda i’n gofyn
will.be I particle ask
‘I will ask / be asking’
Imperfect of verbs expressing mental state
Unlike English, Welsh uses the imperfect of verbs expressing mental states, such as nabod (‘know a person’), gwybod (‘know a fact’) and meddwl (‘think’):
O’n i’n meddwl hynny
was I particle think that
‘I thought so’.
Expressing a more definite intention
To express a definite intention to do something, use na iSM plus the verbal noun:
bydda i’n sgrifennu atat ti ar ôl Nadolig
(‘I’ll be writing to you after Christmas’)
na i’n sgrifennu atat ti ar ôl Nadolig
(‘I’ll write to you after Christmas’—a definite promise)
na is the inflected future of gwneud (‘do’). The 1st person plural form nawn appears in be’ nawn ni? (‘what will we do?’)
Affirmative markers fe and mi
In colloquial Welsh, the particle feSM (southern and central areas) or miSM (northern areas) can (optionally) precede an inflected verb in affirmative statements (but not in questions, negative statements or commands):
fe fydd Sioned yn mynd
PART will.be Sioned PART go
‘Sioned will go / be going’
Time expressions
Table 3. Some time expressions
| Yesterday | Today | Tomorrow | |
| …day | ddoe | heddiw | yfory |
| Morning | bore ddoe | bore ’ma | bore fory |
| Afternoon | pnawn ddoe | pnawn ’ma | pnawn yfory |
| night | neithiwr | heno | nos yfory |
Pnawn is usually written prynhawn. Heddiw is often pronounced heddi.
Amser (‘time’), dydd (‘day’), diwrnod (‘day’), wythnos (fem. ‘week’), mis (‘month’), blwyddyn (fem. ‘year’).
These can be combined with SMbob (‘every’) or trwy’r (‘all’), eg trwy’r dydd (‘all day’)
I haven’t yet found a clear explanation of the difference between the words for ‘day’ (dydd, diwrnod)
I listed the Welsh words for the days of the week and the months alongside the Irish names at https://languagemiscellany.com/2026/08/irish-challenge-7/
