warm
In German, 'warm' is used similarly to English. It can describe a high temperature, as in 'The weather is warm today.' It can also be used metaphorically, such as in 'I received a warm welcome.' Note that German adjectives are inflected based on case, gender, and number, so 'warm' may change depending on its use in a sentence.

This sentence gives a recommendation on how the soup should be served for optimal taste, i.e., it should be served warm and not cold or hot.
