Context & Register
通常用于数学、物理和艺术领域，在日常生活中也较常见。
Pronunciation & Spelling
The words 'geometry' and 'asymmetry' share the '-metry' spelling with 'symmetry' but have different stress patterns (geometry: /dʒiˈɑmətri/, asymmetry: /eɪˈsɪmətri/). 'Industry' and 'country' share the '-try' ending with the same stress on the first syllable, but the vowel after the stress differs; 'industry' (/ˈɪndəstri/) and 'symmetry' both have /ɪ/ as the stressed vowel, while 'country' has /ʌ/. 'History' ends with '-ry' and has a distinct pronunciation (/ˈhɪstəri/). 'Symphony' starts with 'sym-' like 'symmetry' but ends differently, so it is a lookalike with different sound.
