But sometimes an intensive force.
E.g. per-terrere = to thoroughly frighten.

[(3)] Suffixes (other than grammatical inflexions).
A knowledge of the most important suffixes will often help you to the correct meaning of a Latin word, the root of which is familiar to you.
Thus from the √ag = drive, move, we have—
| by addition of | -tor | (= agent or doer of an action), actor = a doer, agent. |
| „„„ | -men | (= acts or results of acts), agmen = a course, line of march, &c. |
| „„„ | -ilis | (= belonging to, able to), agilis = easily moved, agile. |
| „„„ | -ito | (= forcible or repeated action), agito = put in action, agitate. |

[(4)] Cognates, that is, words related in meaning through a common root. You will find it very useful to make for yourself lists of cognate words.
