Variants

Lit(String)

Escape(char)

SQuote(String)

DQuote(Word)

CmdSub(Script)

ProcSub(Script)

Backtick(String)

Arith(Word)

$(( … )). Holds a Word, not raw text, because the body is not opaque: a $( ) inside it RUNS. The arithmetic itself is inert — it can only produce a number, and bash, zsh and dash all evaluate $((id)) to 0 rather than executing id — so the inner command is what decides, and storing parts is what lets the ordinary substitution walkers reach it.
