“名叫”就是“名字叫做”的缩写。正式的书面语和口语中皆可使用，不过偏重正式，因为口语中常常直接说“我叫某某”而不是“我名叫某某”。 我名叫约翰，她名叫爱丽丝。 从前，有一位名叫福尔摩斯的侦探，以精明的逻辑推理而出名。 它是一只名叫嘟嘟的小狗。

Sir, May I ask you a question? Do you ask so many questions on purpose in order to obtain so many points? mingjiao this is only for conversation in general neither for orators nor for formal writing.

My name is Sam. 我的名子叫(是-is) Sam. what should I call you? 請問 (please) ,如何稱呼? 我的姓名是 XX XX XX in whole name not just a nickname. 叫 also means shout. Do you really think shout is formal in English as well??

it's not 名叫， it's 名 叫 = name called 我 名 叫 Sam = my name is called Sam

It literally means "The name is called", like "se llama" in Spanish. It's used more often in written Chinese or story telling. Rarely used in conversation. Most of the time people just use "叫" to introduce a name.
