Phonological features: contraction of must+have to ‘ve.
weak form /məs(t)/ weak form /həv/
a) Because've sounds very much like of, some speakers
sometimes write *must of when must've is actually
the correct form.
b). In fast speech the 've in must've often changes
to a sound that is easier to pronounce. As a result,
must've often sounds something like "musta."
Form: students may confuse the meaning of the form as they tend to be more familiar with the use of must as a modal verb to express obligation (must can’t be used to express obligation in the past) Students may struggle to understand that the form expresses deduction about the past Meaning/concept: Learners may struggle to understand and pronounce the contraction ‘ve Learners may add to (e.g she must’ve to gone out).
Ss may think that must and have refers to an obligation that must be done in the future. This notion may be strengthened by the present use of must have rather than the past.
Students may incorrectly replace the past participle with the base form of the verb (she must have go out).
