ABSTRACT
The PRES and IMPF forms have a special AFF marker y (yr before vowels) that is not present in other tenses. So, for example, CW mae is generally y mae in LW; CW o'n i 'I was' is yr oeddwn, and so on. The LW INT marker ao is used in all tenses-a oeddech? 'were you?', CW o'ch chi?; a ydyw? 'is he/she?', CW ydy e/hi?; a fyddant? 'will they be?', CW fyddan nhw?. The NEG marker in LW for all verbs is ni (AM, or failing that 0 ), nid before vowels, in front of the verb. This is completely at odds with all versions of the living language, where negation is always done by ddim after the verb, and where NEG ni is simply unknown: LW ni fyddant 'they won't be', CW fyddan nhw ddim; LW nid ydwyf 'I am not', CW dw i ddim; LW nid oeddwn 'I was not', CW o'n i ddim.
