Can a kraken cast wizard spells which require verbal and somatic components?

The Kraken, according to the monster manual, can "Understand Abyssal, Celestial, Infernal, And Primordial But Can’t Speak, Telepathy 120 Ft." The Kraken also does not have hands. It seems as if the Kraken can barely cast any spells at all. Can these factors be somehow overcome or explained away, ideally whilst staying within the basic 5e rules?

Does the verbal component for spellcasting have to be words?

To make a long story short: for my first D&D campaign, I want to create a warlock that had to give up her voice as a part of her deal with her Patron.

As such, she is incapable of speaking, but she can still produce sounds with her mouth. I was wondering if that would incapacitate her from casting spells with a Verbal component.

Do spells needs a specific phrase to be cast, or does gibberish work?

Does the Voice of the Chain Master eldritch invocation let me cast a purely verbal spell through my familiar?

In D&D 5e, as a Pact of the Chain Warlock, I can choose an eldritch invocation that lets me speak in my own voice through my familiar called Voice of the Chain Master (PHB 111):

You can communicate telepathically with your familiar and perceive through your familiar’s senses as long as you are on the same plane of existence. Additionally, while perceiving through your familiar’s senses, you can also speak through your familiar in your own voice, even if your familiar is normally incapable of speech.

Healing word is a spell with only a verbal component (PHB 249):

Components: V

[…]

A creature of your choice that you can see within range regains hit points equal to 1d4 + your spellcasting ability modifier.

The description of verbal components in the rules of spellcasting (PHB 203) says the sound of my voice alone is what causes the magic of this spell to happen:

Most spells require the chanting of mystic words. The words themselves aren’t the source of the spell’s power; rather, the particular combination of sounds, with specific pitch and resonance, sets the threads of magic in motion.

Say my familiar is in another room, no matter how far away. Through my familiar’s eyes, I see a target at 60 feet. From my familiar comes my own magic-infused voice. That particular combination of sounds, with specific pitch and resonance, sets the threads of magic in motion that travel to the target and heal it.

Is this possible?

Can a creature under the effect of a Discord Symbol perform verbal spell components?

Symbol allows you to create a magical glyph that triggers on a condition you determine. One of the glyphs you can create is called Discord:

Each target must make a Constitution saving throw. On a failed save, a target bickers and argues with other creatures for 1 minute. During this time, it is incapable of meaningful communication and has disadvantage on attack rolls and ability checks.

Is a creature who fails the save against this effect capable of performing verbal spell components?

Can a Kenku use verbal spells?

A Kenku can only speak by mimicry, so can a Kenku fulfill the verbal portion of spells of his class? I would assume that he could only cast a verbal spell if he has heard the spell be cast by another caster of his same class. Also, the other caster would have to have cast the spell in a way that the Kenku knew what was spoken and why.

Can spells with a verbal component be cast underwater if the caster can’t breathe water?

My party recently tipped over a boat of enemies into what was essentially rapids and trapped the enemies in a cube of force underwater. The warriors inevitably drowned as they had no way out. However, trapped in the cube of force was a wizard with access to a teleportation spell (Misty Step) with a verbal component. Could the wizard use his spell with a verbal component underwater and escape a watery death? If the rules don’t specify anything about verbal components underwater specifically, have any of the designers mentioned anything about this?

Note: as a 5e DM I made a ruling on the spot (decided to allow it on the condition that the caster goes directly from “holding breath” to “suffocating”) so I am aware that it’s within my power to decide how it works in my world. I’d just like to know if the rules or someone wiser than me has addressed this yet.

What is the verbal component of the Dissonant Whispers spell?

This was thought up while reading the following question:

  • Increase the range of Dissonant Whispers

The dissonant whispers spell has only Verbal components and states:

[…] You whisper a discordant melody that only one creature of your choice within range can hear […]

The Sage Advice Compendium document states:

Q. Is the sentence of suggestion in the suggestion spell the verbal component, or is the verbal component separate?

A. Verbal components are mystic words (PH, 203), not normal speech. The spell’s suggestion is an intelligible utterance that is separate from the verbal component. The command spell is the simplest example of this principle. The utterance of the verbal component is separate from, and precedes, any verbal utterance that would bring about the spell’s effect.

Is the "discordant melody" the "mystic words" (verbal component) of dissonant whispers? In other words, is the casting of this spell almost unnoticeable outside of the fact that your lips are moving? What is the verbal component of dissonant whispers?

What would verbal components actually sound like?

Something I’ve always wondered is what does a verbal component actually sounds like in-universe. Is it random sounds, gibberish, or do you anime it and chant something in actual words. Given that the deafened status applies a penalty it’s safe to assume you have to be very accurate when doing your verbal components so I’d like to think it’s not too hard to say. As far as I can find there’s nothing that says what language, length, format etc. Other components are very clear on what you are actually doing and how you are doing it. The answer doesn’t have to be stated directly in the rulebook but it must be from Paizo approved material.

Its also safe to assume spellcraft’s identify function uses other things since spellcraft says “Identifying a spell as it is being cast requires no action, but you must be able to clearly see the spell as it is being cast, and this incurs the same penalties as a Perception skill check due to distance, poor conditions, and other factors.” thus whatever allows you to identify the spell is visual not audible. As far as I know, there’s no description as to what the inside of a spellbook looks like for all we know it could just be a bunch of magic circles. If it actually had words and used the owners language I’d argue you’d have to know the language it’s written in. If it’s in a universal language then I guess that would work but again I don’t know what a spellbook looks like.

What does a verbal component actually sound like in practice?
