Pronunciation: [dˌɪsˈastəɹəs] (IPA) 
The spelling of the word "disastrous" is often misspelled as "disasterous". The correct pronunciation is /dɪˈzæstrəs/.

"Disastrous" is an adjective that describes something as being extremely harmful, calamitous, or extremely damaging in its consequence or outcome. The term is typically used to describe events, situations, or actions that result in significant negative effects or devastating consequences.
When something is deemed "disastrous," it suggests a magnitude of destruction, chaos, or unfavorable impact that exceeds what is considered normal or acceptable. The term often implies a sudden occurrence of a serious and distressing event that leads to far-reaching and severe consequences.
The word can be used to describe a wide range of scenarios, such as natural disasters like earthquakes, hurricanes, or floods, where the massive destruction caused to infrastructure, loss of life, and displacement of communities are considered disastrous. It can also be used to express the devastating outcomes of human actions, such as a disastrous military campaign or a disastrous business decision that leads to financial ruin or significant setbacks.
In a broader sense, "disastrous" can also signify any situation or event that is considered a complete failure, causing significant harm, loss, or distress to individuals, groups, or society as a whole. The term captures the gravity of a situation, conveying the severity and magnitude of its negative consequences.
The word "disastrous" comes from the combination of two separate words: "disaster" and the suffix "-ous".
The term "disaster" originates from the Old Italian word "disastro", which means "unlucky" or "unfortunate event". This Italian word, in turn, was derived from the Latin prefix "dis-" (meaning "away" or "apart") and the word "astrum" (meaning "star"). The ancient Romans believed that the alignment of the stars could influence human lives, and any negative occurrence was often attributed to an unfavorable alignment. Consequently, the Latin term "disastrum" transformed into "disaster" in English and other languages, referring to a calamitous event or misfortune.
The suffix "-ous" is derived from the Latin suffix "-osus", meaning "full of" or "abounding in".
