تسايرا

They two [went, or went along, (see 3,) or] went at an equal rate, or kept pace, each with the other: (PS:) or ran, each with the other. (S, A.)

One says of a great, or frequent, liar, لَا تَسَايَرَهُ خَيْلَاهُ [lit. His two troops of horses will not run together, each troop with the other: meaning (assumed tropical:) his assertions will not be found to agree together]: (so in a copy of the M:) or ↓ لَا تُسَايَرُ خَيْلَاهُ. (So in the K and TA voce خَيْلٌ, q. v.; and so in the TA in the present article [See also 6 in article سلم.])

[And They two vied, contended, or competed, each with the other, in going, or in running: and hence, (assumed tropical:) in any affair.]

One says also, تَسَايَرَ عَنْ وَجْهِهِ الغَضَبُ (tropical:) Anger went [or disappeared by degrees] from his face. (TA, from a tradition)
