أب1 ثُئِبَ, ('Eyn,
T,
M,
K,) like عُنِى
Bَ, (
K,) and ثَئِبَ, (
IKoot,
L, and so in a copy of the
A,)
inf. n. ثَـ
ـأْبٌ, (
K,) or ثَـ
ـأَبٌ, (
M,) He became relaxed and sluggish; said of a man: (
A:) or he became affected with sluggishness and languor; (
M;) as also ↓ تثآءب: (
M, A:) or he became affected with sluggishness and languor like the languor of drowsiness; as also ↓ تثآءب and ↓ تثـ
ـأّب; (
K;) which last is approved by
IDrd and
Thábit Es-Sara- kustee, who disallow ↓ تثآءب, though this is the form commonly known and approved, and is the most chaste form: (
TA:) or he became affected with languor like the heaviness of drowsiness, in consequence of something that he had eaten or drunk, without becoming insensible; (
T;) as also ↓ تثآءب: (
L:) or ↓ this last signifies he yawned, or opened his mouth, (
Mgh,
Msb,) by reason, (
Mgh,) or on the occasion, (
Msb,) of languor (
Mgh,
Msb,) like the heaviness of drowsiness; (
Mgh;) or he yawned, or opened his mouth, and stretched himself, on being affected by sluggishness or drowsiness or anxiety; (
MF,
TA, on the authority of
IDrst;) or he yawned, or opened his mouth, and emitted wind from his stomach, by reason of some affection thereof: (
TA on the authority of EtTedmuree:) التَّثَاؤُبُ is from الثُّؤَبَآءُ; (
Az,
T,
S,
Mgh;) and is on the occasion of one's stretching himself, and being languid: (
Lth,
T:) one should not say تَثَاوَبَ; (
Az,
T,
S,
O,
Mgh;) [for] this is vulgar. (
Msb.) Hence, أَحَدُكُمْ فَلْيُغَطِّ ↓ إِذَا تَثَأَءَبَ فَاهُ [When any one of you yawns, he should cover his mouth with the back of his left hand; for it is believed that the devil leaps into the uncovered yawning mouth]. (
Mgh.) 5 تَثَاَّ^َ see 1.
6 تَثَاَّ^َ see 1, in six places.
ثُؤَبَآءُ, (
T,
S,
M,
K, &c.,) as also ثُؤْبَآء,
accord. to Ibn-Mis-hal, but this is strange, (
TA,) is a
subst. derived from التَّثَاؤُبُ, like مُطُوَآءُ from التَّمَطِّى; (
T;) or from ثَئِبَ; and means A state of relaxation and sluggishness: (
A:) or sluggishness and languor (
M,
K) like the languor of drowsiness: (
K:) or languor like the heaviness of drowsiness, in consequence of something that one has eaten or drunk, not attended by insensibility: (
T,
L:) or a yawning, or opening the mouth, by reason of languor like the heaviness of drowsiness: (
Mgh:) or a yawning, or opening the mouth, and stretching oneself, on being affected by sluggishness or drowsiness or anxiety: (
IDrst,
MF,
TA:) or a yawning, or opening the mouth, and emitting wind from the stomach, by reason of some affection thereof. (Et-Tedmuree,
TA.) Hence the
prov., أَعْدَى مِنَ الثُّؤَبَآءِ, (
S,
A,
TA,) and [الثُّوَبَآءِ,] without ء, as some say; (
MF;) or the pronunciation without ء is vulgar, (
IDrst,
TA,) or erroneous; (
TA;) [More catching than yawning;] for when a man yawns ( اذا تثاءب ) in the presence of others, they become affected as he is. (
TA.) مَثْؤُوبٌ Affected with sluggishness and languor like the languor of drowsiness: from ثُئِبَ,
q. v. (
K.)
