rather than~; more than~
Used to compare two things, emphasizing one over the other, meaning 'rather than' or 'more than'.
よりも is a comparison particle that adds emphasis to the thing being compared against. It is often used to express a preference or a stronger degree of something. When used with nouns, it simply means 'more than [noun]' or 'rather than [noun]'. When used with verbs or adjectives, it often implies a choice of action or state over another.
In speech, you will often hear it shortened to より in casual conversation, but よりも is more emphatic and slightly more formal. It works in both spoken and written Japanese, but is especially common in written essays, speeches, and formal statements to highlight a contrast.
