The spelling of "causing adopt" might seem confusing at first, but it can be explained with IPA phonetic transcription. "Causing" is pronounced /ˈkɔːzɪŋ/ with a long vowel sound, and "adopt" is pronounced /əˈdɒpt/ with a schwa sound. When the two are combined, the "o" in "causing" is replaced with the schwa sound, resulting in /kəˈzɪŋ/adopt/. This deviation from standard spelling, known as respelling, is often used for emphasis or clarification in written language.
