decently

Decently is the adverb form of the adjective decent, which has a few main meanings: it can be used to describe a good, upstanding person (or their actions), or it can mean adequate or passable. These are the senses usually captured by the adverb.

uprightly

To treat others decently involves behaving uprightly, virtuously, properly, or honorably toward them. It often means treating them well, in a way that conforms to the socially accepted standard.

However, decently can also mean adequately.

adequately

To do something decently is to do it adequately, passably, or acceptably. Saying that you’re paid decently usually means that you’re adequately compensated for your work. This implies that the pay is perhaps not great but definitely not bad—it’s decent.

Words similar to this sense of decently are satisfactorily, suitably, sufficiently, and tolerably, though each has different shades of meaning, with some implying a less positive (though not necessarily negative) assessment.
