Firstly, it is tenter hooks, not tender hooks. It means waiting with anxiety. Tenter is a rack for drying cloth and a tenter hook is a nail with an upward curve on which the cloth is hung.
I was on tenter hooks until the test results arrived. Tender hooks do not exist and if they did, they would ne inefective because they are tender.
