英语（English）是印欧语系-日耳曼语族下的语言，由26个字母组合而成，英文字母渊源于拉丁字母，拉丁字母渊源于希腊字母，而希腊字母则是由腓尼基字母演变而来的。英语是国际指定的官方语言（作为母语），也是世界上最广泛的第一语言，英语包含约49万词，外加技术名词约30万个，是词汇最多的语言，也是欧盟以及许多国际组织以及英联邦国家的官方语言，拥有世界第三位的母语使用者人数，仅次于汉语和西班牙语母语使用者人数。

英语由古代从丹麦等斯堪的纳维亚半岛以及德国、荷兰及周边移民至不列颠群岛的盎格鲁、撒克逊以及朱特部落的白人所说的语言演变而来，并通过英国的殖民活动传播到了世界各地。由于在历史上曾和多种民族语言接触，它的词汇从一元变为多元，语法从“多屈折”变为“少屈折”，语音也发生了规律性的变化。在19至20世纪，英国以及美国在文化、经济、军事、政治和科学在世界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，英文的使用更普及。英语是联合国的工作语言之一。 苏格兰语、低地撒克逊语、丹麦语、德语、荷兰语、南非荷兰语和英语也很接近。拥有法国血统的诺曼人于11世纪征服英格兰王国，带来数万法语词汇和拉丁语词汇，很大程度地丰富了英语词汇外，相对也驱使不少原生的语汇作废。
