how do we call

The correct way to ask for the name of something in English is "What do you call this?" rather than "How do you call this?" The phrase "How do you call this?" is not standard English and is often incorrect due to influence from other languages like Spanish. "How do you say this?" is used if you want to know the pronunciation or translation of a word. "How do you call" can be correctly used when referring to making telephone or communication device calls, for example, "How do you call someone on Skype?" In summary, for asking the name of something, use "What do you call...?" and for asking about pronunciation or translation, use "How do you say...?"
