Had Better: Mae'n Well I
Mae'n well i fi fynd means "I'd better go", literally "it's better for me to go".
How It Works
Pattern: Mae'n well + i + person + soft-mutated verb-noun.
- Mae'n well i fi fynd — I'd better go (mynd)
- Mae'n well i ni frysio — we'd better hurry (brysio)
- Mae'n well iddyn nhw ddal y bws olaf — they'd better catch the last bus (dal)
For the personal forms of i, see i fi i ti iddo fe iddi hi.
More gently, with the conditional. Byddai'n well i ti ofyn (South and standard), Basai'n well i chi aros (North): it would be better for you to... See baswn i and byddwn i.
Had better not. Use peidio, which softens to beidio: Mae'n well i ti beidio (You'd better not), Mae'n well i ni beidio â dweud (We'd better not say). See paid â and peidiwch â.
Not the same as "prefer". Mae'n well gen i fynd (North) or Mae'n well 'da fi fynd (South) means "I prefer to go". With i, it means "I'd better go". See mae'n well gen i.

Forgetting the soft mutation.
