Denotation and connotation

Denotation is what a word means; connotation is what it makes the reader feel. Thin, slender, slim, skinny and emaciated all denote low body weight, and no two of them carry the same attitude. Two are neutral, one is complimentary, one is unkind, and one is clinical.

That is why synonym questions rarely have two defensible answers. Several options will match the meaning; only one will match the meaning and the tone of the sentence around it.

The same meaning, different weight

Using context to choose

The sentence usually tells you which shade is wanted, if you read for it.

• Look for a contrast — a "but" or "however" often signals that the missing word opposes something nearby.
• Look for the writer's stance. If the passage is sympathetic, an unkind synonym cannot be right.
• Look at who is speaking and to whom. A patient leaflet and a research abstract call for different words.
• Substitute your choice back into the sentence and read the whole thing. A word that changes the meaning of the sentence around it is the wrong one.
