Ways to tell them apart:
"Essay" is a piece of writing, usually presenting an argument or a point of view, while "assay" refers to the testing or evaluation of a material, usually to determine its components.
Remember "essay" with an extra "e" refers to "express" since it expresses ideas or arguments.
On the other hand, "assay" starting with "ass" can remind you of "assess" as it involves assessing the quality or content of something.
Essays are commonly found in educational settings, whereas assays are often used in scientific contexts.
Both words are pronounced similarly but have distinct meanings based on context.
