ab + solute/ + ly ➔ absolutelyRootsBasesA matrix is a kind of a portrait of a morphological family (words that share a base element). We can think of the matrix as analogous to the “immediate family” (parents and children). On that analogy, an etymological family (words that share a root) is like an “extended family” - a family that includes the immediate family, but also cousins, aunts and uncles, grandparents etc.

Discuss these terms with reference to the the diagram on the next page where every word represented within the oval is in the “extended family” that derives from the same historical root and -- but that extended family can contain multiple immediate families (morphological families).

At right and on the following page are resources I created for a different SWI lesson.

Some semantic interpretations:

See how you can relate the sense and meaning given for the Latin root solv(ere) and the present day English words that derive from that root to the climate crisis.

Some possible orthographic investigations :

Construct a matrix for the base <solve> and another for the base <solute> and place in the appropriate box on the next page.

See if you can find words in this etymological family which do not have a base <solve> or <solute> and write those in the oval on the next page to show they share the root, but not the bases in the rectangles.

Many sources use the terms “root” and “base” interchangeably.

By contrast, in structured word inquiry, “root” is reserved for etymological contexts and “base” is strictly a morphological term.

In other words, in structured word inquiry, the term “base” refers to present day English morphological structures and “root” refers only to the historical source of present day English words.
