Pro Tip 1/3
Context Matters
Often used to indicate that something is barely enough, with no excess. Two sandwiches will suffice for lunch, though there won't be any left over.
Pro Tip 2/3
Minimal Adequacy
Implies completeness, but just to the minimum requirement. If funds are tight, a simple gift will suffice.
Pro Tip 3/3
Humble Tone
Can suggest a modest or non-demanding attitude when used personally. A place to sleep is all that will suffice for me.
