Which root means with, together?

• A. Tachy
• B. Tel
• C. Sym
• D. Sub

Answer: (C)

The form that means with or together is sym-, a variant of the Greek syn- used before b, m, or p to ease pronunciation. It shows up in terms like symbiosis (two things living together), symmetry (things balanced together), and symptom (a sign that accompanies or comes with a disease). The other options don’t convey togetherness: tachy- means fast, tel- (or tele-) relates to distance or end, and sub- means under. So sym- is the one that specifically carries the idea of togetherness.
