When we were investigating the word <diameter>, we came up with an interesting list of words sharing the base element <meter> which means to measure. The original matrix created looked like this:
After looking this over, some wondered if some of the identified prefixes were really base elements with connecting vowels. There was only one way to know for sure! Working in pairs the words were researched with just that question in mind.
This investigation caused us to rethink our original matrix. It also reinforced our motto, ” When we know more, we adjust our original hypothesis.”
With our new evidence, we found four of the words to be compound words with connecting vowels. The remaining question raised is whether or not <meter> can be further analyzed. Several students recognized <er> as a suffix, but the question we have come to ask at that point is, ” Is it a suffix in this word?” The hypotheses suggested by my word investigators were <met> + <er> -> <meter> and <mete> + <er> -> <meter>.
