A juncture is a particular point in a stretch of time or in something you are doing — often an important one, when things could go one way or another. “At this juncture” means “at this point, while things stand like this.” You hear it in news, speeches, and careful writing, not much in easy chat. Though actually the oldest meaning is a physical join, the same family as junction; specialists still use that, but most people only meet the time meaning. It does not mean a road meeting.
關頭、節骨眼（at this juncture ≈ 在這個節骨眼上）
組成From Latin iūnctūra, “a joining,” through Middle English juncture. It is a doublet of jointure: same Latin word, two different paths into English (jointure is now a rare legal word).
