When do I use "New" and when do I use "Knew"?

Is it the adjective meaning recent or not used before? "New". Is it the past of to know? "Knew".

What is the most common mistake with "New" and "Knew"?

"I new it all along" when meaning had knowledge is wrong (correct: knew). And "She had a knew strategy" is wrong for recent: the adjective is "new strategy."

How do I remember the difference between "New" and "Knew"?

"Knew" belongs to the silent-K family: know, kneel, knife, knock. If you know the verb "know," you already know its past "knew" shares the same KN. "New" has no K, just the adjective for recently made.

Did you know?

The K of KNEW (and KNOW, KNIFE, KNIGHT, KNEEL) was actually pronounced in Old English, it was a real /kn-/ sound, normal and audible in Anglo-Saxon English. The K silenced gradually between the 16th and 17th centuries, but by then the printing press had standardized the spelling and fixed it permanently. In German, the same root preserves the pronunciation: "kennen" (to know people) and "wissen" (to know facts) still sound with initial consonants. "Knecht" (servant, squire in German) comes from the same Germanic root as "knight" (in English), both words are cousins that took very different semantic paths.
