I ni ce, @isun !
The words “most”, “least” or the suffix “-est” cannot be translated one-to-one in Bambara.
Your example sentences do not actually use “most” or “least”, but they do point to what you need to use across various sentences of this type: a superlative (“most pleasing”, “fastest”, etc.) construction.
Ideally, the Forum and this category (see the guidelines here) are designed for specific questions (one per thread), related to translating a particular piece of text, rather than seeking a general grammar explanations (or proofreading or full translations).
In practice, this can be tricky. But can you consider reposting with a specific example sentence from English (and it brief context of use) in mind? I hope that makes sense! Yafa n ma!
