Usage of verb abound

I have certain confusions regarding the Verb Abound. Abound is a verb which means to exist in large numbers or amounts. What we generally understand from a Verb is Action. However the Verb abound seems like an aberration where it is depicting a condition or situation. Why is this the case? Why we need such Verbs in English Language when we can simply use Adjectives like abundant?

Abound is a verb, even if it isn't doing what we might consider an "action". A good similar verb would be exist.

Abound really isn't used that frequently though. I (incorrectly) thought it had a negative tone to it as I've only used it ways such as:

Defects and glitches abound in Billy's project that is already too expensive.

Note abound could be replaced with other verbs such as:

• Accumulate
• Exist
• Grow

However, apparently abound can be a positive/neutral as well:

Praise and glory abound in PGSystemTester's project that came in under budget.

Again abound could be replaced with:

• Amass
• Acccumulate
• Exist

Hope that helps.
