Talk:frenulum

Why is the word "fold" used here? It is not a "small fold of tissue" it is a "small thin tissue" that is foldable.

Other definition: "small thin tissue that supports or checks the motion of the part to which it is attached to, in particular a fold of skin beneath the tongue, or between the lip and the gum" --NoToleranceForIntolerance (talk) 04:29, 9 June 2017 (UTC)

From Latin frēnulum, diminutive of frēnum.
Is the diminutive formed by adding -ul- ? --Backinstadiums (talk) 17:05, 2 March 2020 (UTC)
