Hedging: 'Possibly', 'Probably', 'Perhaps'

These three words are adverbs of probability. They tell your listener how much you believe what you are saying. Probably is your high-certainty friend. You are about 75% to 90% sure. Perhaps and possibly are lower on the scale. They sit around 30% to 50% certainty. They change the "vibe" of your sentence without changing the facts. For example, "It will rain" is a bold claim. "It will probably rain" sounds like you actually checked the weather app. Using these words shows you understand that the world is not always black and white. It is like a grammar traffic light. Probably is a flashing green. Perhaps is a cautious yellow.

1. 1For probably and possibly, find the first auxiliary verb. Place the word right after it. "I will probably arrive at six."
2. 2If there is no auxiliary verb, put them before the main verb. "She possibly forgot her keys."
3. 3In negative sentences, probably usually comes before not. "I probably won't go."
4. 4Perhaps is the rebel of the group. It loves to sit at the very beginning of a sentence. "Perhaps we should order pizza tonight."
5. 5You can also put perhaps at the end for a thoughtful after-effect. "We could try again, perhaps."
6. 6When using possibly in a question, it often follows could. "Could you possibly help me with this?"

Use these when you want to be polite in a professional setting. If your boss asks if a project will be done, "It will probably be ready by Friday" sounds more realistic than a flat "Yes." Use them when making guesses about things you cannot know for sure. If you see a crowd, you might say, "There is perhaps an event happening." They are also perfect for giving advice without sounding bossy. Instead of "You should leave," try "Perhaps you should head out now." It feels less like an order and more like a suggestion. Think of it as adding a soft cushion to your words. It is great for job interviews too. It shows you are a nuanced thinker who considers all options.

Do not use these in emergency situations. If a car is heading toward someone, do not say, "You should possibly move." Just yell "Move!" Speed is more important than politeness there. Avoid over-hedging in academic writing when stating a proven fact. Do not say, "The sun probably rises in the east." It just makes you look like you missed primary school. Also, if you are 100% certain and need to show authority, stay away from these. A pilot saying, "We will possibly land soon," might cause a minor panic in the cabin. Use them to be precise, not to sound like you are hiding something.

One big mistake is the "double hedge." You do not need to say, "Perhaps maybe it will rain." Pick one and stick to it! Another classic is putting probably in the wrong spot in negative sentences. Many people say, "I won't probably go," but "I probably won't go" is much more natural. Don't confuse possibly with possibly as a response to "Can you...?" If someone asks, "Can you help?" and you say "Possibly," you might sound a bit rude or lazy. It sounds like you are weighing up if they are worth your time. Stick to "I probably can" or "I might be able to."

Perhaps vs. Maybe: They mean the same thing, but perhaps is the fancy cousin. Use perhaps in writing or formal chats. Use maybe with your friends at the pub. Probably vs. Likely: Likely is an adjective, while probably is an adverb. You say, "It is likely to rain," but "It will probably rain." Possibly vs. Possibly (in requests): In a request like "Could you possibly...?", it doesn't mean "Is it possible?" It actually means "Please be extra kind and do this for me." It is a politeness booster, not a question of ability.
