What word means barely adequate?
When a normal word is used offensively, it can be called a weapon, very much the same as simple tool like a knife or a hammer is used as a weapon to hurt others. Using words as weapons is often called swearing, but the term is barely adequate because the verb to swear also means to make a solemn statement or promise, or to take an oath of office.
The word adequate depends on the judgment of the person using it. Its common meaning adequate means: "Sufficient to satisfy a requirement or meet a need." As people are different and have different requirements and needs the phrase is mainly used to appeal to whoever its being spoken to as most people don't take into account and verify if whats adequate for them is the same adequate being addressed by whoever is speaking about it.
