(A proofreader's note regarding “collaborate” and “corroborate”)

“Collaborate,” “corroborate” begin alike with “co,”
Suggesting that “together” is the only way to go.
“Corroborate” will strengthen, while “collaborate” will work,
“Supporting” then and “laboring,” respectively, the quirk.

“Make stronger now together” is “corroborate” at core,
The added information aiding confirmation more.
But “working close together” with a goal ahead to make –
The essence of “collaborate” when meaning is at stake.
