In a relative sentence, if the relative pronoun is the subject, the verb appears to be in the impersonal form. That is to say, it is always in the form of the third person singular, and does not show any agreement with its antecedent, whatever person or number that may be in. The other peculiarities of relative sentences are given in Chapter VII. §4.
2. “Instead of using the conjunction _that_ with another verb in the indicative mood, as in most European languages, it is usual to put the second verb in the infinitive preceded by the personal pronoun, as is common in Latin.” Thus says Norris, speaking in a manner perhaps rather less clear than usual, of an idiom found in the Dramas. This idiom, analogous to the “accusative with the infinitive” of Latin, is found down to the latest period of Cornish literature, though not to the complete exclusion of a finite clause beginning with _that_. The instances given by Norris are:—
_Ha cous ef dhe dhasserhy_, and say that he is risen.
_Marth a’m bues ty dhe leverel folneth_, I have wonder that thou shouldst speak folly.
_Nyns a y’m colon why dhe gewsel_, it goes not into my heart (i.e. I do not believe) that you have spoken.
_Ny a wel an tîs younk dho e clappya leh ha leh_, { 164} we see that the young people speak it less and less (_Nebbaz Gerriau_).
_Dre wrama crejy hedna dho bos gwîr yu serîfes enna_, { 164} that I do believe that that is true that is written therein (_Nebbaz Gerriau_).
Nevertheless, one finds in the same piece:—
_Ev a lavarras drova gever ǒl_, { 164} he said that it was Goats All.
_Bes mî a or hemma_, _dhort e hoer an Kernuak_, _drova talves bes nebbas_, { 164} but I know this, by her sister the Cornish, that it is worth but little.
And in Keigwin’s translation of _Genesis_ i.:—
_Ha Dew a wellas trova da_, { 164} and God saw that it was good.
A somewhat similar construction is sometimes used after _dreven_, because, and _treba_, until:—
_Dreven tî dhô wîl hemma_, { 164} because thou hast done this (Kerew’s _Genesis_, iii. 14).
_Dreven tî dhô wolsowas dhô dalla dha wrêg_, { 165} because thou didst listen to the voice of thy wife (_Gen_. iii. 17).
_Treba tî dhô draylya dhô’n nôr_, { 165} until thou turn again to the earth (_Gen_. iii. 19).
