Language learning is actually a good example. Words are rarely restricted to their denotative (dictionary) meanings. There are often abstract, connotative meanings attached to them by speakers. For example, consider the following list of words. Hello. Hi. Hey. These words all have the same basic denotative meaning. They're all a greeting. Yet, there is a subtle connotation of formality which is rarely described in a dictionary. These types of connotation are not often understood by beginning language learners. It's something they acquire with time and experience in using the language. While a teacher or search could share about the formalities, the language learner is still going to require time in applying those words in different contexts to fully understand these subtleties.
