حَمَّامٌ

[A hot bath;] a certain structure, (S,) well known; (Msb;) so called because it occasions sweating, or because of the hot water that is in it; according to ISd, derived from الحَمِيمُ; (TA;) i. q. دَيْمَاسٌ: (K:) of the masculine gender, (Mgh, K,) and feminine also, (Mgh,) generally the latter; (Msb;) but some say that it is a mistake to make it feminine, (MF, TA,) though IB cites a verse in which a feminine pronoun is asserted to refer to a حمّام: (TA:) plural حَمَّامَاتٌ; (S, Mgh, K;) according to Sb, [not because the singular is feminine, but] because, though masculine, it has no broken plural (TA.) See also حَمِيمٌ.
