Only one of these is the best choice for the past tense of "slink." Do you know which it is?
Joshua Essoe wrote, “I've been looking, but I cannot find a definitive answer to when one would use "slunk," and when one would use "slinked." I'm of half a mind to declare "slinked" a non-word. What's the difference? When should I use one over the other?”
I can see why Joshua is confused. Different online dictionaries provide different advice about the past tense of “slink”:
Oxford English Dictionary: "slunk"
Merriam-Webster.com: "slunk," also "slinked"
American Heritage Dictionary: "slunk," also "slinked"
Dictionary.com: "slunk" or (archaic) "slank"
I often turn to Garner’s Modern American Usage when I encounter such problems, and Garner’s recommends "slunk," calling "slinked" and "slank" nonstandard. Another one of my favorite books, Merriam-Webster’s Dictionary of English Usage, doesn’t cover the topic.
Based on all these sources, I recommend "slunk" as the safest choice.
Origin of "Slink"
As an aside, I was delighted to discover that the origin of "slink" is the Low German word "slinken." It makes me think of the nursery rhyme “Winkin, Blinkin’, and Nod.”
