Synonyms

Inveterate means established, habitual, or deeply rooted, especially referring to long-standing habits or beliefs. Habitual is the correct synonym. Mild and insignificant are opposite in intensity, venerate means to respect deeply, and simple doesn't capture the sense of something ingrained over time.

Inveigh means to speak or write about something with strong criticism or bitterness. Speak out angrily is the closest match among the options. Help, guide, and enlighten are all positive acts, while overwhelm means to flood - none capture the critical, verbal nature of inveigh.
