The "naming explosion" refers to a period in early childhood development, typically occurring around the ages of 18 to 24 months, when children rapidly increase their vocabulary. During this time, infants can learn an astonishing number of new words each day. Research suggests that children can learn anywhere from 5 to 20 new words a day during this phase.

To narrow it down to one of the provided options:
- **5** words a day seems too low for the naming explosion phase.
- **9** words a day is plausible but may still underestimate the surge during this time.
- **15** words a day is a reasonable estimate based on many studies of vocabulary development during this period.
- **20** words a day is at the upper end but some research has indicated that it might be achievable in particularly verbal infants.

Based on general consensus and research findings, the answer is typically around **15 new words a day**.

### Final Answer
**15** new words a day.
