The correct spelling of "getting sights" is [ˈɡɛtɪŋ saɪts]. It consists of two words: "getting," which is spelled with a double "t" and "-ing" suffix to show continuous action, and "sights," which is spelled with a "gh" to indicate a silent "h" sound and an "s" to signify the plural form. Together, they form a phrase that refers to the act of acquiring or adjusting the sights of a firearm or other sight-dependent tool.
The phrase "getting sights" does not have a specific etymology as it is a combination of two common English words: "getting" and "sights".
"Getting" is the present participle of the verb "get", which originated from the Old Norse word "geta". It entered the English language during the late Middle English period.
"Sights" is the plural form of the noun "sight", which derives from the Old English word "siht". It has been used in English since the Middle English period.
When combined, "getting sights" refers to the act of obtaining or acquiring visual perceptions or views of something.
