Suffix-tin indicates that something is stratched and thin?

You're close! The suffix "-tin" actually indicates "made of tin". It's derived from the Latin word "stannum," which means tin.

For example:

* Tin can: A can made of tin.

* Tin foil: A thin sheet of tin.

The suffix "-tin" doesn't necessarily imply that something is stretched and thin, although it can be associated with those qualities in some cases.
