How to use Until And till:

So first start with English time prepositions until, please make a note that student often misspelled as “untill”. This is bit formal word. We will use this word, when we talk an event or if a situation will continue for up-to certain time. Make a note this words “continue up to”. By checking few example you will get a clear idea about this prepositions.

So let’s look at the example number one, I worked until 5 pm. What we are saying is that, before 5 pm, I was at work, maybe I start to work at 9 am. So from 9 am to 5 pm, I’m at work, and 5 pm I stopped work. So my action of working continued up to 5 pm. After 5 pm I finished.

Look at another example, I can use my wife’s mobile until 8 pm. So what this situation is talking about. It means that I can use this phone, maybe from morning up to 8 pm. After 8 pm, I can’t use it anymore. I’m allowed to use my wife’s mobile up to 8 pm, so that continues up to 8 pm from morning. After 8 pm, I can’t use these phone anymore.

So that’s clear., how to use time preposition until, while we were talking about the situation or an event. As I told you until is a formal word, till is the informal way. It has the same meaning. Till and until can be used interchangeably depending on the context. Till is often used in positive connotation and until in negative connotation. The only thing we need to make sure there should be a specified time.

How to use By:

Now looks some at the expression by, by is similar to until because, they’re both prepositions of time. But they are entirely different. When we were talking about by, we were talking about a situation, or something will happen before or at a certain time. It doesn’t happen after that

So let’s look at some example, I will finish my work by 6 pm. In this sentence, proposition by means before, before 6 pm, or it can mean exactly at 6 pm. But not later than 6 pm.

How to use unless:

The difference between unless and until is, until denote a condition of time, like until 6 pm, or until 4 pm. Unless denotes a condition of an action or context. This proposition is used to state a precondition, or a state of if, except, maybe like. An example is we won’t play unless you are there. That means unless is a word that uses a precondition, you never use it in the negative sentences.

How to use up to:

We could use up to while we were talking about distance and time, choice and finally fit for. Student often misspelled this up to as “up to”. It is not a single word, it is a double word. Let’s see some example. I run up to 5 km. This means you traveled 5 km. It is a distance, 5 km is a distance.  Another example is “he went up to Himalaya”.

How to use a preposition to:

There is no proper rule for this English preposition, What we are going to discuss here is, when to use a preposition” to”. If you want to express a reason, you can use to or for. So you could say I went to the shop to buy fish. If the statement involves any movement or destination we often use a preposition “to”.

How to use still:

Still is an adverb, that is used to describe an action or a situation which continues from past to present, something that is not finished yet. An example is “do you still in the office?” or “do you still driving?”. This adverb always appears in the middle of a sentence. Often it is followed by a verb, sometimes it is followed by an adjective.

How to use adjective yet:

It is always used with negative senescent or with questions. But why we need to use yet, well yet is used to indicate that, something we expect to happen or has happened. Look at this example, they haven’t finished yet. You can see it is a negative sentence. That’s why we are using the adverb yet. Most of the time this adverb yet come at the end of the sentence.
