Lexis refers to units of vocabulary which have a specific meaning,
words have different types of meaning. A single word can have so many different
meaning according to the context.
The meaning of a word may vary for
the variations of its forms, for example we can give an opposite meaning by
adding a prefix, we can change a
word to a comparative o superlative by adding a suffix. This process of adding affixes to the root of a word is called affixation. There are also compound
nouns which are two different words with a single meaning
Inside lexis we have collocations they
are words that usually, and most of the time, go together, idioms which are fixed expressions so they cannot be changed. The
meaning of an idiom can be different from the meaning of the individual words
it contain.
As teachers it is worthy to teach
words in context instead of isolated because we have seen that words have many
different meanings it will be better to let students know in which situation
use the correct word.
I think is a good reflection ruth, you know as teachers we have to teach words in context in order to students can memorize without necessity to study a lot , only with experience it or relate it with their daily lifes it will be enough to get good results in the learning process
