Synonym Chooser

How is the word deduce distinct from other similar verbs?

Where would conclude be a reasonable alternative to deduce?

When can gather be used instead of deduce?

The words gather and deduce are synonyms, but do differ in nuance. Specifically, gather suggests an intuitive forming of a conclusion from implications.
