The spelling of the word "watchings weight" can be confusing because both words have unusual spellings. "Watchings" is the plural form of "watching," and "weight" is spelled with a "gh" instead of a "ght" like most words that end in "ight". In IPA phonetic transcription, "watchings" would be pronounced /ˈwɑːtʃɪŋz/ and "weight" would be pronounced /weɪt/. Always double-check the spelling to make sure you're using the correct version of this phrase, which refers to the weight of something observed over time.
