mētĕr-ŏ-mētĕr

Conventional treatment of -en as null syllable in heav’n, heav’nly, sev’n, sev’nth, giv’n, stol’n, etc.

Conventional omission of vowel or consonant in common function words. Typically eliminates an unstressed syllable. Easily comprehensible but not ordinarily used outside of poetry.

Apheresis (omission of word-initial sounds): until (’til); among (’mong), around (’round), against (’gainst); beneath (’neath).

Syncope (omission of sound within word): over (o’er), never (ne’er), ever (e’er), and derivatives (ne’ertheless, o’erstep, etc.).

Apocope (omission of word-final sounds): often (oft).

Content words with similar contractions are controlled via the “wat’ry, etc.” slider.

Function words that can be syncopated without sounding “poetic” are unaffected by this toggle: every, ev’ry.

See D.G. Miller, English Lexicogenesis (Oxford, 2014), 184–85.

The "e" in -ed suffixes in English words is usually silent, so that punished is pronounced /punisht/ and valved is pronounced /valvd/. (The main exception is when the stem ends in d or t: in words like looted, seeded the "e" is pronounced.) By poetic convention, however, words in which the "e" is usually elided may have that sound pronounced in verse when it suits the meter and when the word is being used as an adjective or a past participle: “some are punishèd,” but not “*I punishèd the offender.” Turn this on to allow this.

This feature depends on the algorithm correctly identifying parts of speech, which it does not always do.

This toggle does not affect words that are already pronounced with an enunciated -ed (such as those mentioned above: looted, seeded), or words in which an enunciated -ed ending distinguishes an adjective from a verb: “a learnèd professor” vs. “I learned from the professor”; belovèd, blessèd, agèd, wingèd. These pronunciations are accepted regardless of the position of this toggle.

Once conventional but now unfamiliar to most readers: devil (de’il), taken (ta’en), open (ope’).

“You make me feel like a na·tu·ral woman.”

Easily comprehensible, but subjectively exerienced as formal, highly poetic, or forced: mis·er·a·ble, mil·li·o·naire, di·a·mond, ca·me·ra, dif·fer·ent etc.

This toggle is for words that are almost always contracted/syncopated in natural speech, but may be fully pronounced in formal or poetic speech.

Easily comprehensible but subjectively experienced as formal, poetic, or forced: watery => wat’ry; conqueror => conq’ror; infinite => inf’nite.

This toggle is for content words that can be contracted/syncopated, but the result sounds unnatural and “poetic.”

This toggle does not affect words that can be syncopated without registering as formal, poetic, or forced — like remembering, which can be pronounced as 4 syllables (re·mem·ber·ing) or 3 (re·mem·b’ring). Both pronunciations sound natural to most native English speakers.
