Is there any difference between nevertheless and never the less?
Solution 1:
Nevertheless is a conjunctive adverb:
: in spite of that : however <her childish but nevertheless real delight — Richard Corbin>
—source Mirriam Webster
Never the less is probably a typo. When it appears as three separate words, it means something quite different. One valid way of using this three-word phrase would be:
You should always select the container that is more full, never the less.
A quick Google NGram search shows that never the less is quite rare.
