替 is written in 12 strokes, following the standard Chinese stroke order. Start from the radical 曰, then complete the remaining strokes.
Stroke order matters in Chinese: it keeps the character balanced, and it is how dictionaries and handwriting input methods expect a character to be written.
替 is an ideographic compound. One man 夫 replacing another; 日 provides the pronunciation.
Radical: 曰 + 8 more strokes
