These are all very subtle! Talk and Speak are basically the same - "I speak to my mother" and "I talk to my mother" are the same, and both are correct. But if you are talking about a language you would never say "I talk English", it is always "I speak English". Tell is used when you are giving someone information: "I will tell you my name if you tell me yours." or "I can't tell you my secret." Study is what you do to learn. In school, studying is reading about things and trying to remember them. When you remember the things you have read, you have learned them. You can study a history book, but you only learn the history in it when you can remember the information in it without reading the book. Fix and repair are the same. They are for physical objects - you fix a car, or fix a bike. Or you can repair a car, or repair a bike. They're all correct. Edit is different to repair and fix - it doesn't mean making something broken work again. It's normally used for text and means to change or correct something written: "I will edit my letter to correct the spelling mistakes." or "I will edit my essay to make it 500 words shorter." I hope this helps!

Talk: speak in order to give information or express ideas or feelings; converse or communicate by spoken words. Speak: say something in order to convey information, an opinion, or a feeling. Tell: communicate information, facts, or news to someone in spoken or written words. from google.com. As you can see, these are very similar. However, there are some slight differences (from english.stackexchange.com). Whether you use speak or talk depends on what kind of communication you have in mind. Originally, speak meant one person informing another. Talk (from tell) originally meant the same thing as speak, but evolved to connote a conversation or dialogue. So speak tends to be used for one-sided communications (e.g. she spoke to her employees), whereas talk implies a conversation or discussion between two or more people (e.g. everyone was talking when he walked into the room). Some examples of grammatical differences are as follows: be talkative ... (be speakative)incorrect speak French ... (talk French)incorrect give a talk ... give a speech (as opposed to a speak) speak up ... talk up (the meanings of the two phrases being completely different, with "up" being a preposition only in the latter case) speaking of which ... (talking of which)incorrect grammatically speaking ... (grammatically talking)incorrect Tell is generally only used as 'tell him, tell her, he TOLD me' etc. Similar to 'inform/informed'. Learn: gain or acquire knowledge of or skill in (something) by study, experience, or being taught. So in order to learn, you must STUDY. Study: the devotion of time and attention to acquiring knowledge on an academic subject, esp. by means of books. (from google.com) Repair, fix and edit was explained very well by Aidan. I hope this helps.
