Many cryptic clues require you to put one set of letters inside another to get to the solution ( i.e. a group of letters “containing” others). There will always be some kind of indicator to suggest that this must be done, and it can be from either point of view — one thing going inside another, or something being on the outside of something else. For example, phrases used in this type of clue include “A in B,” “A caught by B,” “B without A” (“without” here means the opposite of “within”), “A surrounds B,” and “B's entry into A” (“A” and “B” here represent groups of letters and/or words, or possibly a single letter in certain cases, which may have been clued by a variety of the techniques already mentioned above). There are many other words which may be used though.
Exchanged for money without one sound (5) — as a clue for SOLID (sound), which is SOLD (exchanged for money) outside of (without) I (one)
Color captured in instrument (8) — as a clue for CLARINET (instrument), which is CLARET (color) having “captured” “IN”
Holy piece of furniture, with not so much on the inside (7) — as a clue for BLESSED (holy), which is BED (piece of furniture) with LESS (not so much) inside it
