An aldehyde is represented as CHO. It is a carbonyl (C=0) with an H attached.
aldehyde group
An amino aldehyde is an organic compound containing both an amino and an aliphatic aldehyde functional group.
aldehyde
They have the same functional group.
The functional group of an aldehyde is a carbonyl group (C=O) with a hydrogen atom bonded to the carbon atom adjacent to the oxygen atom.

Cinnamaldehyde is an aldehyde. Its structure contains an aldehyde functional group (-CHO) attached to a benzene ring.
An amino aldehyde is an organic compound containing both an amino and an aliphatic aldehyde functional group.
The functional group of citral is the aldehyde (alkanal) group. It has the structure -CHO
From its structure, we can see that vanillin does not have a ketone functional group, but it has an aldehyde. It also has a phenol and ether functional group. For that reason, I wouldn't categorize is as just an aldehyde.
An aldehyde contains a carbonyl group, which is a carbon atom double-bonded to an oxygen atom.

Tollens' reagent or Benedict's solution can be used to test for the presence of the aldehyde group in glucose. These reagents are able to oxidize the aldehyde group in glucose to form a colored precipitate. The appearance of a silver mirror or a red precipitate indicates the presence of the aldehyde group.
The functional groups in vanillin are a hydroxyl group (-OH) and an aldehyde group (-CHO).
