3. Iambic words may become pyrrhics, on account of the stress accent on the first syllable. So dŏmī and căvē have the last syllable short.[13] Trin. 868,
‘Fórĭs pultabo. Ad nóstras aedis híc quidem habet rectám viam’;
Stich. 99,
‘Bónăs ut aequomst fácere facitis, quóm tamen absentís viros.’
4. The stress accent sometimes causes final syllables to be dropped, and so to have no effect on quantity, as in enim, apud, quidem, parum, soror, caput, amant, habent, etc. Trin. 77,
‘Qui in méntem venĭt tibi ístaec dicta dícere?’
Stich. 18 (anapaestic),
‘Haec rés vitae me, sórŏr, saturant.’
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.’
