§10

The main STRESS is normally on the vowel before the last consonant. The plural ending does not change the original stress of the word. Adjectives and nouns ending in -le, -ne, and -re preceded by a vowel have the stress on the third syllable from the end; e.g. fragile, ordine, tempore. In words formed with the suffixes -ic, -ica, -ico, -ide, -ido, -ula, and -ulo, the stress falls on the syllable preceding the suffix. The suffixes -ific and -trico are stressed on the first i.

Deviations from this stress system are covered in the Interlingua-English Dictionary by respelling with stress marks. Most of these deviations might be covered by additional descriptive rules. For instance, the suffixes -issim-, -esim-, -ifer-, and -olog- are stressed on the first vowel. The suffixes -in and -erin, in so far as they correspond to English -y and -cry, are stressed on the vowel i; etc.

Note: Words without consonant or without a vowel before the last consonant are stressed of necessity on the first vowel; e.g. io, via, and certain present-tense forms, as strue, crea, etc. But construe, procrea, etc. and also diminue, substitue, etc. follow the standard rule and have the stress on the vowel before the last consonant.
