This is the verse translation, not a definition of the individual word.
Thus We made you a balanced nation, so that you may be witnesses over mankind and the Messenger a witness over you. We did not change your former direction of prayer [to the Ka‘bah] except to distinguish those who would follow the Messenger from those who would turn back on their heels. It was surely burdensome except for those whom Allah guided. Allah would never let your [acts of] faith go to waste, for Allah is Most Gracious and Most Merciful to all people.
