milligram

key idea

Spelling can be hard sometimes, but it can help to think about the parts in a word.

For example, look at the word parts in centigram, hydrometer, and milliliter.

centi + gram

hydro + meter

milli + liter

These word parts may be called base elements because they have more flexibility than affixes. They can appear in different positions in a word, like tele in telephoto and radiotelegraph. Some base elements, like meter, can even stand alone as words.

To spell, think about each part of the word on its own, then put them together.

centi + gram → centigram

hydro + meter → hydrometer

milli + liter → milliliter

solution

The missing part is gram. The word milligram has these parts:

milli + gram
