Containers

A container inserts one word or letter sequence into another. Containers come in two flavors:

A surrounding B, e.g., around, containing, including
A inside B, e.g., within, entering, wearing

Here are examples of each:

Scam gets Ray sidetracked (8)
Clothing subsidiary owned by men (8)

The first clue has STING (“scam”) surrounding RAY to make ST(RAY)ING. In the second clue, ARM (“subsidiary”) is inserted into (owned by) GENTS to get G(ARM)ENTS.

Note: Many container indicators can also be used to call out hidden words. Which function an indicator serves must be inferred from context.
