Described roughly/uncontrollable fire
Adumbrate is an academic word that is used to foreshadow something to occur, or as it is used in the sentence here, meant to give a vague description or outline of something. The usage of this word is extremely low according to normal corpus linguistic standards. The root of the word is "umbra" and from the Latin, shadow. And as such is the other more frequently used intention of the word - to foreshadow. In this context of foreshadowing, it is meant to tell what is likely to occur in a novel or story line.
Conflagration on the other hand is a powerful fire. It is meant to be used to describe a fire which is incredibly destructive and intense. A good synonym would be "inferno", as this also includes connotations with hell and/or the devil. A conflagration would be a spectacle to watch and in extremely dangerous to be in or around.
<u>Situations that are contrary to fact</u>, the mood is the conditional: third type. Example: If she<u> had got up</u> early, she <u>would not have missed </u>the bus. This example illustrates an imaginary situation; it did not happen. What truly happened was that the woman got up late and missed the bus. This was the fact. The structure is : the condition introduced by "if" carries the Past Perfect and the imaginary result carries would + perfect infinitive.
<u>Conditions under which a situation might occur, </u>the mood is the conditional: second type. Example: If she <u>bought</u> an alarm clock, she <u>would get up</u> on time. This statement reflects a possible solution to a problem; it is a speculative solution. She does not have an alarm clock, yet if she <em>bought</em> one . This is the subjunctive mood . What would the result be? She <u>would get up</u> on time. This is the conditional mood , second type.
