What is the main difference between conceptual metaphors and met

What is the main difference between conceptual metaphors and metaphorical linguistic expressions or linguistic metaphors?
【正确答案】：In the cognitive linguistic view, metaphor is defined as understanding one conceptual domain in terms of another conceptual domain. A convenient shorthand way of capturing this view of metaphor is the following:
CONCEPTUAL DOMAIN (A) IS CONCEPTUAL DOMAIN (B), which is what is called a conceptual metaphor. A conceptual metaphor consists of two conceptual domains, in which one domain (the target domain) is understood in terms of another (the source domain). A conceptual domain is any coherent organization of experience. For example, we have coherently organized knowledge about journeys that we rely on in understanding love, so we have the conceptual metaphor LOVE IS A JOURNEY.
Conceptual metaphors differ from metaphorical linguistic expressions or linguistic metaphors. The latter are words or other linguistic expressions that come from the language of the more concrete conceptual domain, i.e. the source domain.
