Right: 'hǎo' (tone on 'a' as priority vowel)
While words like 'ma' (吗) don't have visible tone marks, they still follow specific pitch patterns that affect meaning.
Some tones change in specific contexts: Two third tones → first becomes second tone (nǐ hǎo → ní hǎo)
'不' (bù) changes to 'bú' before fourth tones
Use Find/Replace in Word to: Find all 'a' and replace with 'ā' for first tone sections Create macros for frequent tone mark combinations Color-code tones (red for 1st, green for 2nd, etc.)
