Hi Ajith, Yeah both of them mean the same but in this sentence, tough talk is not grammatically correct. It's not just the meaning, you have to consider the grammatical aspects also. Hope this helps
Hi Pankhuri, the correct form of the phrase for the sentence would be "tough-talking". Here it is used as a gerund. Hence the verb form should be in continuous form. On the other hand, if it is used as a verb we need to use the following form "He likes to talk tough".
