PERIPHRASIS

The use of a longer expression instead of a shorter one with a similar meaning, for example "I am going to" instead of "I will".

Expressing a grammatical meaning (such as a tense) using a syntactic construction rather than morphological marking.

"Language learners sometimes use periphrases like "did go" where a native speaker would use "went"."

The substitution of a descriptive word or phrase for a proper name (a species of circumlocution).
