occur after the vowel i, but is also restricted from occurring before i in the same morpheme, whereas the Belarusian letter i represents . Later exceptions to these patterns, such as ('poop deck'), ('watt'), East Asian proper names beginning with , and ('Yiddish'), are marginal. The distinction between e and ej carries a light functional load, in the core vocabulary perhaps only distinctive before alveolar sonorants, such as ('peg'), ('cellar'); ('mile'), ('badger'); ('Rhine'), ('kidney'). The recent borrowing ('homosexual') could contrast with the ambisexual prefix if used in compounds with a following consonant, and also creating possible confusion between ('homosexual couple') and ('heterosexual couple'), which are both pronounceable as . is also uncommon, and very seldom contrastive: ('a euro') vs. ('a bit'). Stress and prosody Within a word, stress is on the syllable with the second-to-last vowel, such as the li in ('family'). An exception is when the final -o of a noun is elided, usually for poetic reasons, because this does not affect the placement of the stress: {{lang|eo|fami'li</b>'}} . On the rare occasions that stress needed to be specified, as in explanatory material or with proper names, Zamenhof used an acute accent. The most common such proper name is Zamenhof's own: . If the stress falls on the last syllable, it is common for an apostrophe to be used, as in poetic elision: . There is no set rule for which other syllables might receive stress in a polysyllabic word, or which monosyllabic words are stressed in a clause. Morphology, semantic load, and rhythm all play a role. By default, Esperanto is trochaic; stress tends to hit alternate syllables: . However, derivation tends to leave such "secondary" stress unchanged, at least for many speakers: or (or for some just ) Similarly, compound words generally retain their original stress. They never stress an epenthetic vowel: thus , not . Within a clause, rhythm also plays a role. However, referential words (lexical words and pronouns) attract stress, whereas "connecting" words such as prepositions tend not to: or ('give to me'), not . In ('Do you see the dog that's running past the house?'), the function words do not take stress, not even two-syllable ('which') or ('beyond'). The verb ('to be') behaves similarly, as can be seen by the occasional elision of the e in poetry or rapid speech: ('I'm not here!') Phonological words do not necessarily match orthographic words.
