Synonym Chooser

How is the word deduce distinct from other similar verbs?

Where would conclude be a reasonable alternative to deduce?

The words conclude and deduce can be used in similar contexts, but conclude implies arriving at a necessary inference at the end of a chain of reasoning.

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.
