Usage notes

edit
  • The term is sometimes misunderstood as fine toothcomb, especially in the figurative sense. This form of the expression, and the associated concept of a toothcomb, is often considered erroneous, but fine toothcomb is said to be now “accepted in standard English” by at least the Oxford English Dictionary.[3]
  • Sense 2 (“means of making a thorough search”) is generally used in the form “to go through with a fine-tooth comb”.
