بَدِيهَةٌ

You say, لَكَ البَدِيهَةُ, (K,) in which ISd thinks the ه to be a substitute for ء, (TA,) It is for thee to begin; (K;) and so لك البُدَاهَةُ, with ه substituted for ء. (M, Mbr, TA article بدأ.) And أَجَابَ عَلَى البَديهَةِ (K) He answered, or replied, on the first of his being taken unawares. (TA.) [ عَلَى بَدِيهٍ is mentioned by Freytag, but on what authority he does not say, as meaning Unpreparedly, suddenly, or unexpectedly; and so بَدِيهًا by Golius, as on the authority of J, but I do not find it in the S in the present article.] And رَاهُ بَدِيهَةً, signifies He saw him suddenly, or unexpectedly. (TA.) And بَدِيهَةُ الرَّأْىِ, Suddenly formed, unpremeditated, judgment or opinion. (Msb.)

بَدِيهَةٌ and بُدَاهَةٌ both signify The coming, of speech, without premeditation: and the coming suddenly, unexpectedly, or unawares. (KL.)

And ↓ the latter, [and more commonly the former,] An intuitive knowledge, notion, or idea; such as that one is the half of two; being, with respect to knowledge, like بَدِيعٌ with respect to intellect: (Kull:) [or] the former signifies the faculty of judging rightly at the first of an unexpected occurrence: [intuition, or intuitive perception:] according to ' Alee-Ibn-Dháfir El-Haddád, it signifies primarily اِرْتِجَالٌ فِى الكَلَامِ [i. e. the faculty of extemporizing: or speaking, or composing, extemporaneously, impromptu, without premeditation]: and predominantly, the poetizing, or versifying, impromptu, without premeditation or consideration: except that ارتجال is quicker than بديهة. (TA.) You say, هُوَ ذُو بَدِيهَةٍ (K) He has a faculty of judging rightly at the first of an unexpected occurrence. (TA.) And فُلَانٌ ذُو بَدِيهَةٍ حَسَنَةٍ Such a one has a good faculty of extemporizing; or of uttering, or relating, things by means of the promptness of his intelligence. (TA, in article بدأ: see بَدِيَْةٌ.) And هٰذَا مَعْلُومٌ فِى بَدَايءِهِ العُقُولِ [This is known among the intuitive notions of intellects; i. e., intuitively]. (K, * TA.) بَدَايءِهُ seems to be plural of بَدِيهَةٌ, as in the phrase, (TA,) لَهُ بَدَايءِهُ, i. e. بَدَايءِعُ [He has new, or admirable, things that he utters], (K, TA,) in speech, or language, and poetry, and in answering, or replying: but here it is not improbable that the ه may be a substitute for the ع. (TA.)
