A parser is the person, or much more often the computer program, that parses. The job is the same one you meet under parse: work out the grammar of a word in a sentence, or the grammar of the whole sentence, by naming what each piece is doing. In an old grammar class, the parser might have been the student who stood up and did that by hand.

A parser is the personparser是那個人, or much more often the computer program或者更常見的，是那個電腦程式, that parses那個parse的。The job is the same one you meet under parse這份工作跟你在parse詞條下看到的一樣: work out the grammar of a word in a sentence透過找出一個字在句子裡的文法, or the grammar of the whole sentence或整句話的文法, by naming what each piece is doing透過說出每個部分在做什麼。In an old grammar class在早期的文法課上, the parser might have been the studentparser可能就是那個學生 who stood up and did that by hand站起來，用手動方式做這件事。

Though actually, almost every time you see parser now, it is a machine. A parser reads a line of words or symbols and builds the structure: where a sentence starts, which bit is a name, which bit is a command. Compilers, search boxes, and language tools all use one.

Though actually不過實際上, almost every time you see parser now, it is a machine現在你看到parser這個字時，幾乎都是在講一台機器。A parser reads a line of words or symbolsparser會讀一行文字或符號 and builds the structure然後建構出結構: where a sentence starts句子從哪裡開始, which bit is a name哪一段是名字, which bit is a command哪一段是指令。Compilers, search boxes, and language tools all use one編譯器、搜尋框和語言工具都會用到它。

It is a noun. You do not “parser a sentence”; you parse it, and the parser is what does the work. In computing talk it is a completely ordinary word; in everyday talk outside that world, people rarely need it.

It is a noun它是名詞。You do not "parser a sentence"你不會說「parser a sentence」; you parse it你會說parse it, and the parser is what does the work而parser是做這件事的東西。In computing talk it is a completely ordinary word在電腦用語裡，這是個完全普通的字; in everyday talk outside that world在那個領域之外的日常對話裡, people rarely need it大家很少需要用到它。
