Context & Register
名词。三个常用义项：1）预测（语体中性至正式，常用于商业、经济、气象）；2）投影、放映（语体中性，常用于电影、图像、技术）；3）计划的事业（语体正式，常用于商业计划、科研项目）。综合语体为中性至正式，具体视义项而定。
Pronunciation & Spelling
All listed words end with '-jection' and share the same stressed vowel /ɛ/ and following consonant cluster, thus they rhyme with 'projection'. Be careful with lookalikes like 'protection' (/-tɛkʃən/) or 'direction' (/-rɛkʃən/), which have the same vowel but a different consonant before the vowel, so they do not rhyme perfectly.
