Question

is the group of words in bold a phrase or a clause? tishas suitcase was too large to fit in the overhead bin, so unfortunately she had to check it. phrase clause

Explanation:

A clause has a subject and a predicate (a verb or verb phrase). The bolded part "Tisha's suitcase was too large to fit in the overhead bin" has a subject ("Tisha's suitcase") and a predicate ("was too large to fit in the overhead bin") with a verb ("was"). A phrase lacks a subject - predicate structure. So it's a clause.

Answer:

clause
