The question asks how to write "8" in English.
In English, the digit "8" is simply spelled as "eight". It follows the standard English alphabetic convention where each letter represents a distinct sound or phoneme. For example, 'a' represents /eɪt/ (short "i"), 'b' represents /biː/ (voiced "bee"), and so on. Therefore, to spell "8", we use the letters "e" and "i" twice, in that order.
