Botch means to do something poorly or clumsily, often resulting in a bad result or a mess. It can be used as a verb (to botch a job) or as a noun (a botch of a task). Details and usages:

• As a verb: to spoil something by doing it badly or carelessly. Example: "They botched the repair and the leak returned."
• As a noun: a badly done piece of work or a mistake. Example: "That patch job is a real botch."
• Common phrases: botch up (phrasal verb) means to mess something up.

If you’d like, I can tailor definitions to a specific sense (e.g., formal dictionaries vs. everyday usage) or provide example sentences.
