What is one benefit of using idiomatic expressions in language learning?

Using idiomatic expressions in language learning significantly enhances understanding of cultural nuances. Idioms are often deeply rooted in the cultural and social contexts of a language. By learning these expressions, language learners gain insights into the thoughts, behaviors, and values of native speakers. This understanding helps learners navigate conversations more effectively and enables them to engage in cultural discussions with greater depth, fostering better communication and connection with speakers of that language.

The other responses, while relevant to language learning in some respects, do not capture the distinct advantage that idiomatic expressions provide in terms of cultural comprehension. Instead of simplifying communication or making it less formal, idioms typically add layers of meaning and context that reflect the unique characteristics of a culture. Additionally, while memorization can be a part of learning idioms, they are not inherently easier to memorize than other phrases; their complexity and context often require more nuanced understanding than straightforward vocabulary.
