Identify the correct spelling of the INCORRECTLY spelt word in the given…

In 'spot the misspelt word' questions, every word in the given sentence must be checked against its accepted dictionary spelling, paying close attention to compound words, silent letters, and words that sound alike but are spelled differently.

In this sentence, the word rendered as “byepass” does not match its accepted dictionary spelling. The correct form is a compound built directly from “by” + “pass” (denoting a route around an obstruction, as in a well-known type of heart surgery), with no extra vowel inserted between the two parts. The remaining words in the sentence — “synthetic”, “plastic”, and “artery” — are all rendered in their standard dictionary spelling.

• synthetic — derives from the Greek “synthetikos” ('put together'); its standard spelling uses the digraph “th” and a single “t” before the “-ic” ending.

• plastic — derives from the Greek “plastikos” ('able to be moulded'); its standard spelling ends in “-stic” with a single “t”.

• artery — derives from the Greek “arteria”; its standard spelling uses a single “r” and a single “t” followed by “-ery”.

• bypass — a compound built from “by” + “pass” (a route around an obstruction); its standard spelling has no extra vowel inserted between the two parts.

Hence, the correctly spelled version of the incorrectly spelt word in the sentence is bypass.
