An important point or detail is pertinent.
When we talk about something being pertinent, we usually mean that it's relevant and useful for the situation. We often use this word to describe information, comments, or questions that are directly connected to what's being discussed. For example, if you're planning a trip and someone asks, "Is the weather in Paris important?" The answer might be, "Yes, it's pertinent because we don't want to get caught in bad rain." In a meeting at work, someone might say, "This data is pertinent to our current project," meaning that it has something useful to add.
Important with regard to (a subject or matter); relevant
