Teaching guide: how to practise sentence analysis
Analysing a sentence shows how it works: who or what it is about, what the verb says and what goes with it. This free sentence analysis worksheet generator makes printable worksheets with sentences written for each level and analysed with British school grammar terms (subject, verb, object, complement, adverbial); the answer key draws each analysis as boxes or as a tree. For verb forms, try the verb tenses worksheets; for word order in the early grades, the sentence building worksheets.
Student worksheet 
Answer key Objects and adverbials
Direct and indirect objects, complements after linking verbs and adverbials of time, place and manner; object complements at level 3.
Full analysis
Noun, prepositional, adjective and adverb phrases with their job in the sentence and the words inside them: determiner, head, modifier, preposition.
Boxes or a tree
Choose how the analysis is drawn: boxes under the sentence or a sentence tree above it.
Sentence types
Statements, questions, commands and exclamations; linking, transitive and intransitive verbs, and passives.
One right analysis
Every sentence is chosen so it has one analysis: no phrasal or prepositional verbs, no indirect objects with to, and exclamations that start with What or How.
Frequently asked questions about the sentence analysis worksheets
Which grades are these worksheets for?
Grades 6 to 10. Level 1 (subject first; objects, complements and adverbials of time, place and manner) suits grades 6 and 7; level 2 (fronted adverbials, questions, commands, exclamations) grade 8, and level 3 (passives and object complements) grades 9 and 10.
What is the predicate?
Everything in the sentence except the subject: the verb and the objects, complements and adverbials that go with it. When an adverbial comes first (After lunch, the children played football), the predicate is in two parts, around the subject.
What is the difference between an object and a complement?
An object follows an action verb and is a different thing from the subject (Lucy bought a dress). A complement follows a linking verb such as be, look or seem and describes the subject (These flowers look fresh). An object complement describes the object (They named the puppy Biscuit).
What does an implied subject mean?
Commands have no written subject: in Close the window, the subject is you. The answer key writes it under the analysis.
Can I get a sentence tree instead of boxes?
Yes: in More options, choose Tree. Only sentences whose predicate is in one piece are used for trees, so branches never cross.
How do I print only the answer key?
Tap Print and choose “Answer key”, or “Worksheet and answer key” to get both. Select the exercise and tap “New” for new sentences with the same settings.
