Correct spelling for the English word "Strale" is [stɹˈe͡ɪl], [stɹˈeɪl], [s_t_ɹ_ˈeɪ_l] (IPA phonetic alphabet).
The word "strale" is derived from Middle English "stral(e)", which in turn originated from Old English "strǣl" and Old Norse "stráli". These terms were used to refer to an arrow or a dart.
The ultimate origin of the word can be traced back to the Proto-Germanic word "*stralaz", which meant "arrow". This Proto-Germanic term likely comes from the Proto-Indo-European root "*stere-", which had the sense of "to rush" or "to strive". This root also gave rise to words in other Indo-European languages relating to "quickness" or "hurling", such as Latin "torus" (a throw) and Sanskrit "srāti" (he hurries).
Over time, the meaning of "strale" evolved to refer to a slender beam of light or even a beam of lightning.
