PROBLEM: I am writing a report where I want to say something like: The number of structures in the PDB has been steadily increasing, with nearly 140 thousand structures currently available. However, this number feigns in comparison to the number of unique protein sequences that have been discovered, with over 210 million unique sequences present in the UniParc database. However, I am not sure about the 'this number feigns in comparison to' part. I have a feeling that I am using the wrong word here, but googling around didn't give me any leads.

SOLUTION: Pales in comparison, I suspect. To pale in comparison is to look weak, small, meagre, or inferior compared to something else. Pale here takes the little-used sense to become smaller. It's the same pale used in the common phrase (less common in the U.S.) pale into insignificance, whose meaning is obvious. (says Grammarist.com)

PROBLEM: I'm trying to describe a situation in which a person prepares for an event, then realises the event won't happen, and so they undo their preparations, returning to a state of unpreparedness. Whenever I search for the opposite of 'prepare', I get words that describe a failure to prepare in the first place, or at best words that describe what happens to the preparations, not words that describe what happens to the person. Is there a word that captures what happens to the person as they return to a state of unpreparedness?.

SOLUTION: There is the phrase 'stand down' about which Lexico says stand down PHRASAL VERB 2 Relax or cause to relax after a state of readiness. If something doesn't happen soon, I reckon they'll stand us down. An ambulance crew was dispatched immediately, however they were stood down shortly after. They have got to accept that the war is over and stand down their army once and for all.

PROBLEM: I want to know what the longest palindrome word is.

SOLUTION:
Detartrated. Edit: surprise, surprise, Wikipedia has more: The longest palindromic word in the Oxford English Dictionary is the onomatopoeic tattarrattat, coined by James Joyce in Ulysses (1922) for a knock on the door. The Guinness Book of Records gives the title to detartrated, the preterit and past participle of detartrate, a chemical term meaning to remove tartrates. Rotavator, a trademarked name for an agricultural machine, is often listed in dictionaries. The term redivider is used by some writers but appears to be an invented or derived termonly redivide and redivision appear in the Shorter Oxford Dictionary. Malayalam, an Indian language, is of equal length. So let's see: tattarrattat (onomatopoeic) detartrated Rotavator (trademark) redivider (disputed) Malayalam
