Types
English
In English traditional grammar types, three types of object are acknowledged: ''direct objects'', ''indirect objects'', and ''objects of prepositions''. These object types are illustrated in the following table:
Note that indirect objects are frequently expressed as objects of prepositions, complicating the traditional typology; e.g. "I gave salt ''to the man''."
Other languages
Some
Chinese verbs can have two direct objects, one being more closely bound to the verb than the other; these may be called
"inner" and "outer" objects.
Secundative language
A secundative language is a language in which the recipients of ditransitive verbs (which takes a subject and two objects: a ''theme'' and a ''recipient'') are treated like the patients (targets) of monotransitive verbs (verbs that take only one ...
s lack a distinction between direct and indirect objects, but rather distinguish primary and secondary objects. Many African languages fall into this typological category.
Syntactic category
While the typical object is a pronoun, noun, or noun phrase, objects can also appear as other
syntactic categories A syntactic category is a syntactic unit that theories of syntax assume. Word classes, largely corresponding to traditional parts of speech (e.g. noun, verb, preposition, etc.), are syntactic categories. In phrase structure grammars, the ''phrasal ...

Identification
A number of criteria can be employed for identifying objects, e.g.:
::1. Subject of passive sentence: Most objects in active sentences can become the subject in the corresponding passive sentences.
::2. Position occupied: In languages with strict
word order
In linguistics, word order (also known as linear order) is the order of the syntactic constituents of a language. Word order typology studies it from a cross-linguistic perspective, and examines how different languages employ different orders. C ...
, the subject and the object tend to occupy set positions in unmarked declarative clauses.
::3. Morphological case: In languages that have case systems, objects are marked by certain cases (accusative, dative, genitive, instrumental, etc.).
Languages vary significantly with respect to these criteria. The first criterion identifies objects reliably most of the time in English, e.g.
::Fred gave me a book.
::a. A book was given (to) me.
—Passive sentence identifies ''a book'' as an object in the starting sentence.
::b. I was given a book.
—Passive sentence identifies ''me'' as an object in the starting sentence.
The second criterion is also a reliable criterion for

In linguistic typology, an analytic language is a language that conveys relationships between words in sentences primarily by way of ''helper'' words ( particles, prepositions, etc.) and word order, as opposed to using inflections (changing th ...
s such as English, since the relatively strict word order of English usually positions the object after the verb(s) in declarative sentences. In the majority of languages with fixed word order, the subject precedes the object. However, the opposite is true for the very small proportion (approximately 2.9%) of the world's languages that utilize

In linguistic typology, object–subject (OS) word order, also called O-before-S or patient–agent word order, is a word order in which the object appears before the subject. OS is notable for its statistical rarity as a default or predomi ...

Verb classes
Verbs can be classified according to the number and/or type of objects that they do or do not take. The following table provides an overview of some of the various verb classes:
:::::
Ergative and object-deletion verbs can be transitive or intransitive, as indicated in the following table:
::::::::::
The distinction drawn here between ergative and object-deletion verbs is based on the role of the subject. The object of a transitive ergative verb is the subject of the corresponding intransitive ergative verb. With object-deletion verbs, in contrast, the subject is consistent regardless of whether an object is or is not present.
In sentence structure
Objects are distinguished from subjects in the syntactic trees that represent sentence structure. The subject appears (as high or) higher in the syntactic structure than the object. The following trees of a
