What you name a string of glyphs (letters) regardless of their meaning and regardless of their pronunciation?
for example in Persian
سیر represents following words (and more):
/siɾ/a unit of weight (75g)
These words are homonyms or heteronyms, or in English
- moped /ˈmoʊpɛd/ n. a small motorcycle
- moped /ˈmoʊpt/ v. past tense of mope
What you name
سیر: some letters that are written representation of one or more morpheme?
Update: to clarify what I am looking consider following table, what you name first column?
(?) number of words ------ ---------------- moped 2 dog 1 does 3
Update 2: In languages that are written use Arabic script short vowel generally are not written, as a result most strings represent more than one word.
