FoxType’s Sentence Tree is free online tool that creates a relational tree diagram of parts of speech it identifies in a given sentence. This is a free tool among many trial based tools that FoxType offers (which I would’ve gladly covered had they been free) in its package. You’ll basically enter a sentence in the space provided and its tree diagram will be generated below. The tree diagram will mark the parts of speech in the sentence and connect them with the appropriate relationship.

How to use FoxType’s Sentence Tree

Foxtype’s Sentence Tree will take a huge load off teachers because it makes a relational tree diagram out of a sentence’s parts of speech. FoxType’s other tools only allow a certain percentage of usage except for Sentence Tree. Click on Sentence Tree tab to start using it. You’ll already see a sample sentence already illustrated on the page. Users can use the mouse wheel to zoom in and out of the diagram. Let’s take simpler examples to check it out.

I used the four different types of sentences recognized by English grammar to see FoxType in action: Declarative, Imperative, Exclamatory and Interrogative. If you don’t know what they are, read here.

I used a short declarative sentence-‘I like Pizza’. Here is what the Sentence Tree mapped:


The Sentence Tree keeps ‘like’ at the top as it is verb holding the whole sentence. You can see the tree also mentions the subject, object and their nature. Here, ‘I’ is a personal pronoun used as a nominal subject while ‘Pizza’, a proper noun is the direct object.

Here is another example:

imperative sentence tree

Sentence Tree marks the possessive pronoun which is used as a possession modifier in an imperative sentence. It also marks the preposition that connects the base form verb ‘go’ with the rest of the sentence.

sentence tree exclamatory

I combined the other two sentences in one sentence. This is where FoxType’s Sentence Tree faltered. It failed to recognize ‘my’ and ‘god’ in the exclamatory sentence with their respective part of speech even when the exclamatory part was an interjection. The rest of the sentence was properly tagged with the right part of speech.


Here is a sentence that uses all 8 parts of speech. ‘Playing’ is the gerund verb in present participle tense that keeps the whole sentence huddled. Each word is properly marked with their nature and relation with respect to other words. You can now test yourself by manually figuring out the parts of speech of any sentence, then running that sentence in FoxType’s Sentence Tree for the right answer. Compare both of them to see how you did!

I also tested it with a grammatically incorrect sentence. I expected Sentence Tree to show an exception about the wrong sentence. However, it marked the grammatically incorrect sentence with the correct parts of speech too.

Final Words

This is one of the best tools to teach and learn about the parts of speech. Usually it’s a bit complicated when you have to identify adverbs, nouns, prepositions, adjectives, etc in complex sentences. With FoxType’s sentence tree, identifying parts of speech is much simpler and will train your mind to identify them. You might find a few words wrongly identified in bigger sentence but those chances don’t pop up too much. I award this tool with 4.9 Stars.
