Bib (garment)

A bib is a garment worn hanging from the neck on the chest to protect clothing from accidentally spilled food. Bibs are frequently used by young children, especially infants, but also by some adults. Bibs are also worn when consuming certain "messy" foods. In addition, bibs are used for infants when they drool a lot, for example when they are teething.
Etymology.
The word, reported in English since 1580, probably stems from the verb bibben "to drink" (c.1380), from the Latin "bibere", either because it was worn while drinking or because it "soaked up" spills.
Other uses.
Part of garment.
The term bib may also refer to the part of a garment that covers the chest. For instance, an apron that covers the chest may be referred to as a bib apron. The part of a jumper dress or of an overall that covers the chest may also be referred to as a bib.
Sports.
In sport, it may refer to a garment that used by a team to identify themselves on the field of play (a jersey), or to identify a participant in a competition with a start number ("bib number"). In netball, bibs are used by the umpire to identify players' positions so it can be determined who is within their allowed area.
Medical.
Paper bibs are also commonly used in dentist offices to protect the patient's clothing during checkups and cleanings. Another medical use is during an x-ray, a lead bib can be put over a patient to prevent the radiation from reaching parts other than the part of the body being tested.
