having trouble seeing the print?

The Talmud connects the name of the Purim story’s heroine, אֶסְתֵּר
– Esther – with the concept of concealment, the root of which is ס.ת.ר (s.t.r). Here’s a Wikipedia article containing various explanations for the name of אסתר.
Deriving from the ס.ת.ר root, we have the verb לְהַסְתִּיר
– to conceal or to hide. להסתיר is an active-causative הִפְעִיל verb.
For example:
She concealed the information from the media.
Something concealed is מֻסְתָּר
– a passive-causative הֻפְעַל gerund.
For example:
He is carrying a concealed weapon.
A synonym of להסתיר is לְהַחְבִּיא
– to hide (something), usually referring to hiding something physical.
