Increasingly means more and more as time goes on. Not a lot yet, but the direction is clear.
It is one of the workhorses of journalism and academic writing, and it usually sits before an adjective, giving increasingly difficult, increasingly rare, increasingly common. Its usefulness is that it describes a trend without needing a figure, which is also why careful readers treat it with suspicion. It can begin a sentence, as in increasingly, people are working from home. The verb is increase and the opposite trend word is decreasingly, which is rarely used.
