The terminations of infinitives in _-eir_ have become _-oir_, except where the form has been reduced to that of the first conjugation; and those of imperfects and conditionals (imperfects reduced all to one form) have regularly _oi_ instead of _ei_. There is no intermixture of _ei_ and _oi_ inflexions, such as we find in Angier, in the _Vie de S. Auban_, and in Bozon. In a few isolated instances we have _ai_ for this _oi_ of inflexion, as _poait_ in _Mir._ 795, _solait_ 10605 &c. (which last seems to be sometimes present rather than imperf.), and _volait_ 13763. Also occasionally in other cases, as _curtais_, 5568, in rhyme with _mais_, _mesfais_, &c., elsewhere _curtois_, _array_, 18964, rhyming with _nay_, _essay_, usually _arroy_, and _desplaie_, _manaie_, _Bal._ xxvii. 2, elsewhere _desploie_, _manoie_. There is however nothing like that wholesale use of _ai_ for _ei_ (_oi_) which is especially characteristic of Langtoft, who besides the inflexion in _-ait_ has (for example) _may_, _cray_, _ray_, for _moi_, _croy_, _roi_. In ante-tonic syllables we may note the _ei_ of _beneiçoun_, _freidure_, _leisir_ (usually _loisir_), _Malveisie_, _peitrine_ (also _poitrine_), _veisin_ (beside _voisin_), _veisdye_, &c., and _ai_ in _arraier_, _braier_. iv. The diphthong _oe_ (_ue_) is written in a good many words, but it may be doubted whether it had really the pronunciation of a diphthong. The following list contains most of the words in which it is found in the tonic syllable: _avoec_, _boef_, _coecs_ (coquus), _coer_, _controeve_, _demoert_, _doel_, _joefne_, _moeble_, _moel_, _moet moeve_ (from _movoir_), _moers moert moerge_ (from _morir_), _noeces_, _noef_, _noet_, _oef_, _oel_, _oeps_, _oevre_, _poeple_, _poes poet_, _proesme_, _soe_, _soeffre_, _soen_, _troeffe_, _troeve_, _voegle_, _voes_ (also _voels_), _voet_ (also _voelt_). In the case of many of these there are variations of form to _o_, _u_, _ue_, or _ui_; thus we have _cuer_ (the usual form in the _Mirour_), _controve_, _jofne_, _noces_, _owes_ (dissyll. as plur. of _oef_, also _oefs_, _oes_), _ovre_, _pueple_, _pus_ (also _puiss_), _puet_ (also _poot_), _prosme_, _sue_, _truffe_, _trove_, _volt_, and (before an original guttural) _nuit_, _oill_ (oculum). Two of these words, _cuer_ and _oel_, occur in rhyme, and they both rhyme with _ẹ_: _mortiel_, _oel_, _fraternel_, _viel_, 3733 ff., and _cuer_, _curer_, _primer_, 13129 ff., by which it would appear that in them at least the diphthong sound had been lost: cp. _suef_ in rhyme with _chief_, _relief_, _Bal._ L. 2. The same rhyming of _cuer_ (_quer_) occurs in the _Vie de S. Auban_, in Langtoft and in Bozon (see M. Meyer’s introduction to Bozon’s _Contes Moralizés_). With _avoec_ we also find _aveoc_ and _avec_, _veot_ occurs once for _voet_, and _illeoc_, _illeoque(s)_, are the forms used from Lat. _illuc_. v. French _ọ_ (_eu_, _ou_) from Latin _ō_ (not before nasal).
