Saint Ignatius High School

Etymology Word of the Week

Director of Admissions Pat O'Rourke '90, a self-proclaimed "word nerd," brings you his Etymology Word of the Week. Every other week he presents an online Etymology lesson just for fun!

Etymology Word of the Week – As some of you know, in addition to working in the Admissions Office, I also teach Latin at Saint Ignatius and am something of a "word nerd."  Thus, each week, I’ll sneak a vocabulary word (sometimes derived from Latin, sometimes not) into the e-blast.  Here then is this week’s edition of the Etymology Word of the Week.  

Dilate - “to make wider or larger; to cause to expand.”   From the Latin prefix dis- meaning “apart, away, in a different direction” and the Latin adjective latus, -a, -um meaning “wide, broad, extended.”  (All information is from www.wikipedia.org, www.etymonline.com and/or www.dictionary.com.)

RELATED WORDS/PHRASES – latitude, latissimus dorsi (widest muscle of the back); BUT NOT lateral (this word comes from the Latin noun latus, lateris meaning “side or flank (of a body)”

SAMPLE SENTENCE - “The cartoon wolf’s eyes dilated when he saw a pig driving a motor car.”
