Do the following sentences have the same voice form? Are they passive? And do they use the same tense? simple past?

The clothes were folded and the room was cleaned.

The clothes were folded by him.

Is "folded" a verb or adjective? or there is another part of speech we can use to describe it. (in this context)

There is no simple way of saying if the word “folded” is an adjective or a verb in these sentences. Linguists are still arguing about the concept of part of speech as applied to cases like this. So I'll try to give a reasonably theory-neutral description of how words like "folded" are used, and then summarize the mainstream part-of-speech analysis in the last section of my answer.

Terminology in this area is also not entirely fixed, so I'll refer to words like folded and eaten using the theory-neutral term "-ed/-en words".

Passive -ed/-en words can be interpreted in two major ways

There are clearly at least two fairly distinct ways to interpret these sentences.

  1. Eventive/dynamic: The most likely interpretation of “The clothes were folded” in the first sentence is that it narrates an event: an action done by an unspecified actor. That is, it would be more or less equivalent to “Someone folded the clothes.”

  2. Stative/static: But it could also describe a state resulting from an prior, already-finished action, more or less equivalent to “Someone had folded the clothes.”

Similarly, the second sentence is most likely to mean “He folded the clothes”, but it would be possible for it to mean something more like “He had folded the clothes”.

While these are, as I said, fairly distinct conceptually, they are often very similar in meaning, so in many cases it's not possible to determine which interpretation was intended by the speaker or writer of a sentence.

Factors that force a stative interpretation

There seem to be some things that cannot be combined with the eventive interpretation, and therefore force a stative interpretation. I know of two that might be relevant for "folded":

  1. The adjectival negative prefix "un-": A sentence like "The clothes were unfolded" (meaning "the clothes were not yet folded"), has to be given a stative interpretation.

  2. Using the word as a gradable adjective: there are various ways to do this. It includes using a comparative form, or putting the adverb "very" before the word. These are not very likely to be used with "folded", but if someone did say "The clothes were very folded" or "the clothes were more folded than I thought", only a stative interpretation would be possible.

Do these two interpretations correspond to different parts of speech?

In phrases describing a state, there is as far as I know consensus that the word “folded” should be classified as an adjective.

In phrases describing an event, the mainstream analysis is that “folded” should be classified as a verb. But other viewpoints do exist.

It’s my understanding that, while the term “participle” can be used to refer to both categories of -ed/-en words, it is often reserved for the words of this form that are eventive and classified as verb forms in mainstream grammar; the stative adjectives may be called something else like “participial adjectives” to mark them as a distinct type of word.


It is a participle.

An explanation of participles can be found here.

A participle is a lexical item, derived from a verb, that has some of the characteristics and functions of both verbs and adjectives. The adjectival form of the term participle is participial.

    What about : "The folded shirts were placed in the suitcase."?

  • I should add, I am truly asking. I am horrible with grammar. My guess is folded shirts makes folded an adjective.

    Hmm, I have done some further research and it seems as though they can be used as both verbs and adjectives. Although there doesn't seem to be any decent source pointing out exactly how it should be defined. My best guess would be to call it a participle and leave it at that. Jan 26, 2017 at 17:19
