英语（English）属于印欧语系中日耳曼语族下的西日耳曼语支，由古代从欧洲大陆移民大不列颠岛的盎格鲁、撒克逊和朱特部落的日耳曼人所说的语言演变而来，并通过英国的殖民活动传播到世界各地。根据以英语作为母语的人数计算，英语是最多国家使用的官方语言，英语也是世界上最广泛的第二语言，也是欧盟，最多国际组织和英联邦国家的官方语言之一。但仅拥有世界第三位的母语使用者，少于官话汉语和西班牙语。上两个世纪英国和美国在文化、经济、军事、政治和科学上的领先地位使得英语成为一种国际语言。如今，许多国际场合都使用英语做为沟通媒介。英语也是与电脑联系最密切的语言，大多数编程语言都与英语有联系，而且随着网络的使用，使英文的使用更普及。英语是联合国的工作语言之一。
英语语法是针对英语语言进行研究后，英语语法系统地总结归纳出来的一系列语言规则。英语语法的精髓在于掌握语言的使用。
