To interpret the meaning of the word "semiannual," we start by examining the prefix "semi-". According to the table provided:
- The prefix "semi-" means "half in value" or "happening once halfway through a specific time period."
Given this, "semiannual" can be broken down into two parts:
- "semi-" meaning half or halfway
- "annual" meaning year (derived from "annum" in Latin)
Putting these together, "semiannual" indicates something that happens halfway through a year or every half-year.
Since a year consists of 12 months, dividing this by 2 gives us 6 months. Therefore, an event occurring semiannually would take place every 6 months.
This means that the women's club held fundraisers two times within a single year period.
Hence, the correct interpretation of the word "semiannual" in this context is:
twice a year.
