No shortening, however, takes place when the accent goes back to the antepenult (cf. _continē_), nor in words like _aetas_, _mores_, where the first syllable is long, nor even in _abi_, _tene_, _tace_, and the like, when the chief accent is weakened, i.e., where these words are pronounced slowly and emphatically (especially before a pause). _Asin._ 543, 'Intro abī: nam té quidem edepol níhil est inpudéntius.' 5. This influence of the chief accent affects also combinations of two monosyllabic words which make an iambus, and combinations like _ego illi_, _age ergo_, in which the second syllable of the second word is elided. _Trin._ 354, 'Is ĕst inmunis, quoí nihil est qui múnus fungatúr suom'; _Trin._ 133, 'Non égo ĭlli argentum rédderem? Non rédderes'; _Stich._ 237, 'Adíbo ad hominem. Quís haĕc est quae advorsúm venit?' 6. The chief accent could also affect a preceding syllable. In polysyllables or polysyllabic combinations, when the chief accent was on the third syllable, the second syllable, if long, could be shortened, provided the first syllable were short. _Trin._ 456, 'Ferĕntárium esse amícum inventum intéllego'; _Stich._ 59, 'Néc volŭntate id fácere meminit,' etc.; _Stich._ 179, 'Per ănnónam caram díxit me natúm pater.' 7. The following common words have to be separately considered, _ille_, _iste_, _unde_, _inde_, _nempe_. In the last three the liquid was practically dropped; _iste_ was pronounced as _ste_; and in _ille_ only one _l_ was heard, cf. _ellum_, _ellam_ (_en-illum_ = _en-ilum_ = _en-lum_ = _ellum_). _Frustra_ is a trochee, as in _Menaech._ 692 (at the end of a line), _frústră sis_; and the first _i_ of _fieri_ is long. Cf. _Trin._ 532, 'Si in ópserendo possint interfīeri.' 8. An original long vowel is sometimes kept when later authors have it short. Examples are, _es_ (from _esse_), final _-or_, as _exertitor_, _fateor_, _ecastor_; verbal endings, as _eris_, _eget_, _sit_, _det_, _fuat_, _velit_. 9. _Synizesis._ _Deus_, _meus_, _tuos_, _suos_ (nom.), _eius_, _ei_, _eum_, _quoius_, _quoi_, _huius_, _huic_, _rei_, etc., may be monosyllables; _deorum_, _meorum_, _duorum_, _fuisti_, etc., may be dissyllables; _diutius_, _exeundum_, etc., may be trisyllables. Other examples are _proin_, _proinde_, _praeoptare_, _dehortor_, _aibam_, _quator_. 10. _Hiatus._ This occurs, though not frequently, (_a_) at the natural division of the metre. _Menaech._ 219, 'Spórtulam cape átque argentum. | éccos treis nummós habes.' (_b_) At the natural break in the sense, especially with change of speakers. _Trin._ 432, _PH._ 'Tempúst adeundi.' _LE._ 'Éstne hic Philto qui ádvenit?' The hiatus is commonest in monosyllabic words, or words ending in a short syllable followed by _m_, making the first syllable of an arsis resolved into two shorts. _Trin._ 433, 'Is hérclest ipsus. Édepol _ne ego_ istúm velim'; _Trin._ 305, 'Quí homo cum animo inde áb ineunte aetáte depugnát suo.'
