Morphology

a + mouthful

The phrase builds on the literal compound 'mouth' + '-ful' (an amount that fills the mouth) and the meaning 'a word or phrase that is long or hard to say' is a natural metaphorical extension of that image. Because the sense requires this figurative mapping rather than strict compositional meaning, it is partially predictable to learners who know the parts but not fully transparent.

Etymology

The phrase a mouthful comes from the image of having your mouth full of food, so you cannot speak clearly. So we call a very long or 'hard to say' word a mouthful.
