I argue irrespective/irrespectively of what I do.

Question

Which word do I choose?

Answer 1

I'd choose a completely different word! I'd choose "regardless."

The sentence seems meaningless, though. What are you trying to say? What is the context?

Answer 2

Yes, this sentence is meaningless. My original sentence is actually very different; I wanted to know if I use the adjective or adverb in this case. But yes, I think I'll use "regardless" now.

But still, for future purposes...which word do I use?

Answer 3

I'd use the adjective form ... AND a comma after "argue," too.

Answer 4

Okay, thanks!

Answer 5

You're very welcome!
