Assuming a var called name and a suffix of -123

Host = “${var.name}-123”

You can concatenate them directly or using join. For example:

variable "id" {
  default = "abcde"
}

output "output1" {
  value = "${var.id}id"
}

output "output2" {
  value = join("", [var.id, "id"])
}

which will give:

output1 = abcdeid
output2 = abcdeid
