(TA.)

جِيسَ also signifies It (anything) was trodden: جَوْسٌ is said to be like دَوْسٌ: (TA:) and you say, جَاءَ فُلَانٌ يَجُوسُ النَّاسَ Such a one came stepping over the people; synonym يَتَخَطَّاهُمْ. (A, TA. *) And according to A' Obeyd, جُسْتُهُ and حُسْتُهُ both signify I came into it, and trod it; (خَالَطْتُهُ وَوَطِيءْتُهُ;) meaning, any place. (TA.) You say also, جَاسَهُمُ الأَسَدُ The lion trod upon them: or came into the midst of them, and did mischief among them. (TA; [in which the verbal noun of the verb in this sense is said to be جَوْسٌ and جَوْسَاءُ: but the latter is probably a mistranscription for جَوَسَانٌُ.])
