Answer:
The answer is primary metaphors.
Step-by-step explanation:
Primary metaphors are based on a clear, side by side comparison of two concepts. This way, the meaning is fairly easy to interpret and does not require any specialised knowledge (that could happend in root metaphors, which are specific to a culture or identity) nor overanalysis, as could occur with complex metaphors.
Something interesting is that many primary metaphors may be considered by some as dead metaphors, which have become so familiar to readers that its use is now seen as "cheesy".
