When you’ve escaped, congratulations are due, because you’ve managed to get away from or out of something threatening or dangerous. Escape means to free yourself from confinement or restraint (an ingenious plan to escape from jail, a need to escape from reality) or to succeed in avoiding capture or any other danger (escaped the police, escaped detection). Fleeing does not necessarily entail escape, although people certainly flee with the intention of escaping. When you flee, you run away—on foot or using any means of transportation. Flee usually implies running away from peril or from pursuers, whether the danger is explicitly stated or not (waited for a chance to flee, fled from the police). Flee can also mean to leave a dangerous person or place (fled the country, fled the scene).

When we describe something as suggestive, we mean it suggests or calls up thoughts or ideas of other things. (His recommendation was suggestive of his boss’s thinking.) Redolent can be used to similar effect, although redolent denotes calling up memories as well as thoughts of something else (verse redolent of Shakespeare, an atmosphere redolent of the McCarthy era). You may have encountered redolent in its more common literal meaning of “pleasantly fragrant” (redolent lilacs) or “odorous or smelling of” (redolent of garlic). Given the unique power of olfactory memory, it is not surprising redolent acquired a meaning similar to suggestive. Redolent is also used with the preposition “with,” to mean steeped in or imbued with either a smell or a quality (a song redolent with nostalgia).

The verb crack means "to figure out or solve," as in crack a murder case or crack a code. Cracking a code suggests being able to decipher messages written in the code without possessing the key or algorithm beforehand. Unless it’s aimed at the daily cryptogram in the newspaper, cracking is generally a hostile action—or heroic, depending on which side you’re on. Decrypt, which is the inverse of encrypt, means to translate a coded communication back into its original, readable form (decrypted the message). Decrypt has been used in reference to deciphering a message with or without a key. In the context of the digital age, it is almost overwhelmingly used to mean with the key. These days, data and files are being automatically encrypted and decrypted constantly, in the effort to conceal them from those who would crack them.
