Other places you find a women as a harlot using the same hebrew word:
It is used as wife in some cases here.

Ezekiel 16:34-35
And the contrary is in thee from other women in thy whoredoms, whereas none followeth thee to commit whoredoms: and in that thou givest a reward, and no reward is given unto thee, therefore thou art contrary. Wherefore, O harlot, hear the word of the LORD:

Ezekiel 23:47-49
And the company shall stone them with stones, and dispatch them with their swords; they shall slay their sons and their daughters, and burn up their houses with fire. Thus will I cause lewdness to cease out of the land, that all women may be taught not to do after your lewdness. And they shall recompense your lewdness upon you, and ye shall bear the sins of your idols: and ye shall know that I am the Lord GOD.

Hosea 1:2
Go, take unto thee a wife of whoredoms and children of whoredoms: for the land hath committed great whoredom, departing from the LORD.

Amos 7:17
Therefore thus saith the LORD; Thy wife shall be an harlot in the city, and thy sons and thy daughters shall fall by the sword, and thy land shall be divided by line; and thou shalt die in a polluted land: and Israel shall surely go into captivity forth of his land.
