مَسْهَجٌ

[like مَسْهَكٌ] A place where the wind passes along [or blows violently]. (AA, S, O, K.) AA cites, as an example, the saying,

إِذَا هَبَطْنَ مُسْتَحَارً مَسْهَجَا

[When they descend into, or enter, a place of confusion, or perplexity, where one is unable to see his right course, a place where the wind blows, or blows violently]. (S, O.)
