语境与语域Context & Register
语域：neutral 常见场景：agriculture、public health、product labeling insecticide 是比较正式的用语，多用于农业、公共卫生或产品说明等书面语境；日常口语中更常说 bug spray，或用含义更广的 pesticide。选择时需注意语境。
发音与拼写Pronunciation & Spelling
side and decide are genuine sound matches because the final stressed syllable /saɪd/ matches insecticide's secondary-stressed ending. The other -cide words share the same spelling and ending sound, but their primary stress falls earlier, so they are not perfect rhymes. Do not let the -cide spelling fool you: pesticide, suicide, homicide, and herbicide do not fully rhyme with insecticide.
