What is the difference between implicit and explicit meaning? Answer: It's simple that the reader infers details that are implied by the text, Explicit means clearly expressed or readily observable where as Implicit means implied or expressed indirectly. 由網路可知,明顯和隱含是這兩個字的意思。 Tacit:adjective 1.understood without being openly expressed; implied: tacitapproval. 2.silent; saying nothing: a tacit partner.3.unvoiced or unspoken: a tacit prayer. Origin: 1595–1605;< Latin tacitussilent, past participle of tacēreto be silent(cognate with Gothic thahan;akin to Old Norse thegja ) Related formstac·it·ly, adverbtac·it·ness, noun Synonyms 1. unexpressed, unspoken, unsaid, implicit. Antonyms 1. expressed.可知,這字的意思和implicit是一樣的。但我覺得英文常常和老外的習慣用法有關,這個句子他們覺得用tacit比較好吧~
