Large substituents decrease basicity due to sterics, but some methyl or ethyl groups would increase basicity, right? Because they're electron donating?

Any other particles about amines that we should we aware of?

nucleophilic addition of an amine to an aldehyde makes an imine, and to a ketone makes an enamine, correct?

Btw Imine is a primary amine. Enamine is a secondary amine.
