Fastened or chained I fastened my bicycle to the tree. I chained my bicycle to the tree. (For American English)

Hi Sol, For the first question, I would say: "You can lock your bicycle to the tree" or "I locked up my bike to the bench" or "I'll chain my bike to the post." I would usually say "lock" or "locked up" or "locked to" for a bike/bicycle as you are usually using a bike lock. If your bike lock is a chain type lock, you may say "chain" or "chained to" or "chained up." For an animal, for example a dog, I would not use "lock" though. For a dog I would usually use "tie" or "tied up" or "tied to." For example, "She tied up her dog to the tree outside." or "I'll tie my dog to the bench while we go inside." If it is a big dog, who may have a chain type leash instead of a rope type leash, you could instead say "chain" or "chained up" or "chained to." I hope that helps!

When you are describing the "action" of fastening a bike to a tree or fence in English, we usually use the phrase of "locking it up" "I am going to lock my bike up, to that tree." "I have just locked my bicycle to that post over there." "I secured my bicycle to that post with a lock and a chain." Informally,..we might use a word like "fastened or hitched" "I hitched my dog and bike to the same tree." Hitched or fastened when used would come across as improper grammar, but still would be descriptively accurate...but in English the words locked up or secured or chained up would be more preferred to describe the action of "fastening a bike". As for dogs, livestock such as cows and pigs are usually described as being "tied up" because they are living creatures and bicycles are machines. For most sentences this is the easier way to think of it. When we fasten an animal to a tree or post with a leash or rope. We might say something like.. "I tied my pet dog to that tree next to where I locked up my bicycle." "My dog is tied to that post beside my bike." "I locked up my bike and secured my pet dog to the tree." I hope this helped you!

Greetings, Fasten means-to (cause something to) become firmly fixed together, or in position, or closed: Make sure your seat belt is securely fastened. This shirt fastens at the back. fasten sth on, together, etc. ​ --> to fix one thing to another: I fastened the sticker to the windscreen. If you want to tie your animal , you can say Fasten/chain/lock this animal /cycle with chain. All expressions are correct. Hope it would help! Regards, Mantra Deepika
