The grammar pattern からして attaches to nouns and has two main usages: expressing a basis for judgment and highlighting a representative example.
からして is used to express that based on a particular piece of evidence, one can draw a conclusion or make a judgment. It often implies that the speaker is making an inference from what they can observe.
In this usage, からして is similar to からはんだん判断すると ("judging from") but is more concise and common in spoken Japanese. The conclusion that follows is typically the speaker's subjective opinion or inference.
からして can also mean "even", highlighting that even the most basic or obvious example already has a certain quality – implying that everything else is the same or worse. This usage carries a strong nuance of emphasis, often with a negative connotation.
Here, the speaker picks out the most fundamental or representative element to show that if even that is problematic, everything else must be too.
Context usually makes the meaning clear. When からして is followed by a conclusion or inference, it means "judging from." When it emphasizes that even the cited example already demonstrates a problem or quality, it means "even / starting from."
