|Unicode name||ARABIC LETTER TEH MARBUTA|
ة (تَاء مَرْبُوطَة (tāʾ marbūṭa))
- It mostly exists in grammatically feminine words. It always follows a fatḥa ـَ ("a") and in pausal speech has no other sound in modern Arabic, a /t/ is added in genitive construct (إِضَافَة (ʾiḍāfa)) and it changes to a normal ت (tāʾ), when a suffix is added, e.g. غُرْفَة (ḡurfa, “a room”) -> غُرْفَتِي (ḡurfatī, “my room”) (غرفة (ة -> ت) + ـي).
- When desinential inflection is used in Classical Arabic or in the formal MSA, non-pausal ة is pronounced as /t/ (preceded by usually unwritten fatḥa "a") and has -u/un, -i/-in, -a/an case endings, e.g. لُغَةٌ - "luḡa" (pausal and informal), "luḡatun" formal, non-pausal pronunciation (nominative case, indefinite).
- Adverbials from tāʾ marbūṭa don't add alif (ا) with fatḥatān, fatḥatān is attached directly to tāʾ marbūṭa, the "hidden t" is pronounced with the ending "-an" e .g. عَادَةً (ʿādatan, “usually”).
- In a more relaxed orthography ة is replaced with ه (hāʾ) with the same pronunciation, especially in Egypt and Sudan.
- Loanwords from words with tāʾ marbūṭa use "at", "ah", "a" and "e" endings.
