Four methods for vocab

I teach my student four methods of figuring out words they don't know.  

Cognates:  amenazar is menace (threaten).  English has lexicon from French and Latin, so it has a lot of Romance language cognates. 

Morphology: breaking the word down into its parts. Destejer is unweave. Desagradablemente is des agrada ble mente.  Un pleas ant ly.  The word will have a root, a core meaning, and prefixes and suffixes. You can understand amenzar better if you take away the a- prefix.  Like amanecer is related to mañana.   

Context. You guess the word from its surrounding words, or just ignore a word you don't know and go on.  

The 4th way?  Repetition.  You find the word over and over again and eventually figure it out. That doesn't work for seeing the word once in a very short text.
