Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
“All bark and no bite” contrasts threatening or forceful talk with little corresponding action. This guide keeps the current figurative meaning separate from any exact-origin claim.
“Close but no cigar” is an informal expression for an attempt that came near to success or correctness but did not quite achieve it. The modern meaning is published without claiming an exact inventor or first occurrence.
“A dime a dozen” is a chiefly US idiom for something very common, easy to find, and not especially distinctive. The wording can carry a dismissive tone when it suggests that something is readily replaceable.
“A drop in the bucket” describes an amount that is very small compared with what is needed or compared with a much larger whole. Cambridge labels it as the US form and gives “a drop in the ocean” as the UK counterpart.
