1. One in the same
Think of it! This one makes no sense whatsoever!
Somewhere along the way, it became a (incorrect) replacement for the phrase 'one and the same'
One and the same is often used in place of 'the same thing'.
One in the same is incorrect. Period!
Instead say: One and the same
Eg: Brinjal and aubergine are one and the same.
2. On tender hooks
Tenters were wooden frames used to dry woollen cloth.
As way back as the 14th century, after the cloth was woven, it would have to be cleaned of oil from the fleece and dirt.
The cloth would then have to be left to dry so it wouldn't shrink and would be stretched on the tenter using tenterhooks.
Tenterhooks were basically hooked nails driven through the wood to which were fixed the edges of the cloth so as it prevent it from shrinking and losing shape.
When someone leaves you on tenterhooks, it suggests a state of tension, not unlike the figuratively stretched cloth on the tenter.
Instead say: On tenterhooks
Eg: I was on tenterhooks because she didn't call me for two whole days!
