How is it pronounced? HiDAri or hidaRI? The slow and normal version sound different...
....in Japanese you pronounce all syllables with the same rythym, i.e without putting stress on a single syllable
I speak Spanish, so l can remember 左 as left because エ looks like a "I" of "Izquierda" and I remember 右 as rigth because ロ reminds me a "D" of "Derecha" hehehe
The way I remember the meaning in English is seeing "e" as both the second letter in left and the katakana エ in the kanji.
That's JUST what I came to comment! Yes, I think this is a very good way to memorize the character, have my lingot, good sir!
