How to say "to breathe" in Arabic

Root נ-פ-ש / ن-ف-س, matched letter for letter — but the two languages breathed it in different directions. Arabic kept the literal sense, 'to breathe'; Hebrew's נפש became 'soul' (the breath that animates a body), while the verb הִתְנַפֵּשׁ survives narrowly as 'to rest, catch one's breath' (Exodus 31:17, וַיִּנָּפַשׁ). Everyday Hebrew 'breathe' is נשם, a different root.
