Schwa in the context of "List of Dutch loanwords in Indonesian"

In phonetics, vowel reduction is any of various changes in the acoustic quality of vowels as a result of changes in stress, sonority, duration, loudness, articulation, or position in the word (e.g. for the Muscogee language), and which are perceived as "weakening". It most often makes the vowels shorter as well.

Vowels which have undergone vowel reduction may be called reduced or weak. In contrast, an unreduced vowel may be described as full or strong. The prototypical reduced vowel in English is schwa. In Australian English, that is the only reduced vowel, though other dialects have additional ones.

Diacritical marks of two dots ¨, placed side-by-side over or under a letter, are used in several languages for several different purposes. The most familiar to English-language speakers are the diaeresis and the umlaut, though there are numerous others. For example, in Albanian, ë represents a schwa. Such diacritics are also sometimes used for stylistic reasons (as in the family name Brontë or the band name Mötley Crüe).

In modern computer systems using Unicode, the two-dot diacritics are almost always encoded identically, having the same code point. For example, U+00F6 ö LATIN SMALL LETTER O WITH DIAERESIS represents both o-umlaut and o-diaeresis. Their appearance in print or on screen may vary between typefaces but rarely within the same typeface.
