استشعرت البَقَرَةُ

The cow uttered a cry to her young one, desiring to know its state. (A, TA.)

And استشعروا They called, one to another, uttering the شِعَار [by which they were mutually known], in war, or fight. (TA. [See also 4.])

استشعر as synonym with اشعر and تشعّر: see 4, in the latter half of the paragraph.

Also, (A,) or استشعر شِعَارًا, (K,) He put on, or clad himself with, a شعار [i. e. an innermost garment]. (A, K.) [Hence,] اِسْتَشْعِرْ خَشْيَةَ اللّٰهِ (tropical:) Make thou the fear of God to be شِعَارَ قَلْبِكَ [i. e. the thing next to thy heart]. (TA.) And استشعر خَوْفًا (tropical:) He conceived in his mind fear. (S, A. *)
