Understanding the Roots string and strict
The Latin word stringere, which means "to draw tight" or "to bind," usually appears in English words as the root strin. However, it can also be spelled stra and stric. For example, something that is astringent draws together body tissues and stops the flow of blood or other secretions. Something restricted is confined within limits. Regardless of their spelling, all the words from this root share a similar meaning, "being pulled together."
