The spelling of the word "most depending" is incorrect. The correct form is "most dependent," with the final syllable pronounced as "dent." This phonetic transcription is /dɪˈpɛndənt/. The incorrect spelling may arise from confusion with the verb "to depend," which is spelled with an "ing" ending when used in the present participle form. However, in the comparative form of the adjective "dependent," the correct ending is "-ent," not "-ing."
