提供 (tígōng) is the most common everyday verb for 'to provide, offer, supply' — used broadly for services, information, meals, etc. It is more general than 供应 (gōngyìng, HSK6), which emphasizes continuous supply of goods or resources (e.g., water, electricity), and 供给 (gōngjǐ, HSK6), which is formal/economic supply (e.g., provisions). 供 (gōng, HSK7) is rarer as a standalone verb and often appears in compounds like 提供.
