: : : : What does it mean to "Go off on a Tangent" or "Wild Tangent"? Please help.

: : : When people are having a discussion and one is said "to go off on a tangent" it means that that person has deviated or diverged from the original purpose of the discussion.
: : : It is mathematical in origin.

: : The line that touches the straight one (in the diagram) but curves away after just touching it is called a "tangent" from the La**n "tangere," to touch. Christ said "Noli me tangere" (in the Vulgate), meaning "Don't touch me." Among the words derived from "tangere" is contingent. SS

: Yes, the word tangential has numerous cousins: tax, contact, attain, intact, tact, taste, tangible, tactile. What's common in all is the idea of touching (or not, as in case of "intact").

: (I had to edit out the "t" and "i" above as Google spiders this URL frequently and people start asking for translations which clogs things up)

Sometimes I just cannot think of the word I want, and that was the case of the past participle of tangere. As soon as my post was submitted it came back to me. Thanks for naming some of the numerous derivatives of tangere. But you have used a locution totally unfamiliar which looks as though it must be useful. What does it mean to "spider" a URL? Thanks in advance. SS
