It appears in lots of places, but the rules are not always obvious.\n\nAfter question words, we often use *to* + infinitive: for example, \"I don’t know (1) .......... to say\" or \"Can you show me (2) .......... to do it?\" This structure is common when the subject is the same person.\n\n*To* is also used after certain adjectives. It’s natural to say \"I’m happy (3) .......... help\" or \"She was surprised (4) .......... hear the news\". Without *to*, these sentences sound incomplete.\n\nFinally, some verbs are followed by *to* + infinitive, but others are not. For instance, we say \"I forgot (5) .......... lock the door\" (meaning I didn’t lock it), and \"He decided (6) .......... leave early\". However, with *stop*, the meaning changes: \"stop (7) .......... smoke\" means quit the habit, while \"stop to smoke\" means pause in order to smoke.\n\nIf you pay attention to these patterns, you’ll soon know (8) .......... to use *to* and when not to.","When to Use \"to\"",{"1":8,"2":13,"3":17,"4":22,"5":25,"6":28,"7":31,"8":35},[9,10,11,12],"when","how","what","which",[14,15,10,16],"whether","where","why",[18,19,20,21],"for","to","that","in",[18,23,19,24],"of","with",[26,19,27,18],"on","about",[29,19,30,18],"as","so",[19,32,33,34],"-ing","out","up",[10,12,36,11],"who",72,{"id":39,"username":40,"first_name":41,"last_name":42,"image":43},20425,"gamze-pisgin","gamze","pişgin","https://lh3.googleusercontent.com/a/ACg8ocKWlQY70Z6X_kUQM4K_PIppbhQ_RXjZGdRGjs5rjBUIdQZzCccUOg=s96-c","B2","Reading","Multiple Choice","multiple-choice","The use of \"to\" (after question words, after adjectives, and after some verbs such as forget and stop).","Standard",{"times_played":51,"num_favorites":52},3,0,"2026-02-26T16:11:43",null,false]
