Recognize five entry-level Latin roots: act, port, struct, ject, form

Introduce five Latin roots and their meanings — ACT (do), PORT (carry), STRUCT (build), JECT (throw), FORM (shape). Use the root-meaning DETECTIVE routine: find the root, recall its meaning, combine with prefix/suffix to predict the whole-word meaning, check the dictionary. Build small word-family maps (act → action, react, actor, actress, active).

Common misconceptions
  • Assigns the wrong root-meaning to a familiar word ('export' → 'out + carry' ✓ vs. mistakenly 'out + airport-style').
  • Believes every short letter-sequence is a Latin root (false positive: 'cat' inside 'catalog' is not a root).
